Where's the 'task manager' on a mac.

New to Mac and looking for the Task Manager? Apple's equivalent is Activity Monitor---we'll show you where it is and and how to use it.

Quick Links

Terminating stubborn programs with "force quit", troubleshooting with more detail: activity monitor.

If you're a veteran of Windows, you're probably familiar with using Task Manager to deal with applications that freeze or checking memory usage. On a Mac, those tasks fall to a Force Quit dialog or a utility called Activity Monitor , which has shipped with every version of Mac OS X and macOS since 2000. Here's how to use them.

If you're familiar with pressing Ctrl+Alt+Delete on a Windows PC to kill a stubborn program, you'll be glad to know that a similar three-finger combo exists on the Mac. When a program becomes unresponsive, simply press Command+Option+Esc to open the "Force Quit Applications" dialog .

A window will pop up that lists currently running apps. To close a stubborn one that refuses to quit normally, select it from the list, and click the "Force Quit" button.

After asking for confirmation, macOS will close the application you selected. Very handy.

If you have a deeper system resource issue to look into on a Mac, such as memory consumption or detailed information on a particular app or process, you'll want to use Activity Monitor. By default, Activity Monitor lives in a folder called "Utilities" within your Applications folder on your Mac.

One of the fastest ways to open Activity Monitor is by using Spotlight. To open "Spotlight," click the small "magnifying glass" icon in your menu bar (or press Command+Space).

When the "Spotlight Search" bar appears, type "activity monitor," and hit "Return." Or you can click the "Activity Monitor.app" icon in the Spotlight results.

Once the "Activity Monitor" window opens, you will see a list of all the processes running on your Mac, similar to this:

Using the five tabs across the top of the window, you can visit displays that show information on running processes sorted by CPU usage ("CPU"), memory usage ("Memory"), energy usage ("Energy"), disk usage ("Disk"), and network usage ("Network"). Click the tab corresponding to the section you'd like to visit.

At any time while listing processes, you can select a process from the list, and click the "Stop" button (which looks like an octagon with an "x" inside it) to force it to quit, or click the "Inspect" button (an "i" in a circle) to see more information about the process.

And if you're overwhelmed by the number of processes listed, you can narrow them down using the "View" menu up in the menu bar. For example, you could select "My Processes," to see only a list of processes associated with your user account.

You can also search for a process using the search bar in the upper-right corner of the window. Just type in the name of the app or process you're looking for, and it will appear in the list (if it is currently running).

Activity Monitor is very handy, so take some time to explore it, and you'll become that much more adept at using it to troubleshoot your Mac . Have fun!

For seasoned Windows users, it’s common to launch Task Manager and close apps and background activities to speed up the system. But if you have recently switched from Windows to Mac, you might wonder where the task manager on Mac is. Don’t worry; macOS has its own task manager equivalent, and in this guide, I’ll show you all the possible ways to open it.

Where is task manager on Mac?

The task manager on Mac is called Activity Monitor . Part of the reason why many new Mac users fail to find it is because of this macOS terminology.

Activity Monitor is a built-in Mac tool that functions like Windows Task Manager. It displays resource usage to offer insights into your system’s performance.

By opening Activity Monitor on a Mac, you can monitor real-time CPU, memory, disk space, energy consumption, and network usage. If your Mac is lagging , you can even close some unresponsive apps and diagnose the issue behind it.

1. Using Spotlight Search

This method is often considered a shortcut to open Activity Monitor on Mac.

• Press the  Command + Spacebar  keys to access Spotlight Search.

Compared to Windows’s poor search algorithm, which sometimes takes hours to deliver a search result that is often wrong, the  Spotlight on Mac  is quick and accurate.

2. Using Finder

The Finder on Mac works in the same way as “This PC” on Windows, where you can find anything and everything present on your Mac, including the Activity Monitor.

• Open the  Finder  app on your Mac.
• Click on  Applications  under the Favourite section in the left Window pane.

3. Using Launchpad

The Launchpad on your Mac is just like the home screen or App Library on your iPhone or iPad. Unlike Windows, each program or utility is available as a separate app on Mac, and the same is the case with Activity Monitor.

• Launch Spotlight (cmd + space bar), type Launchpad , and hit return .

Alternatively, you can a gesture to open Launchpad. On the trackpad, just pinch in using your Thumb and Three Fingers.

4. Using Dock shortcut

Now that you know how to access the Activity Monitor from the Launchpad, you can easily add the Activity Monitor app to your Dock if you need to access it frequently.

• Drag the  Activity Monitor  app icon from the Launchpad and place it in the  Dock .

5. Using Terminal

You can also use a command line to launch the Activity Monitor app on your Mac.

• Open the Terminal  window via Spotlight Search or Launchpad.

• Hit the return key.

6. Using Siri voice command

While Siri may not be the best voice assistant available, it is undoubtedly the best to quickly complete a task with a simple voice command.

If you often  use Siri on your Mac , you will find this as the easiest way to open the task manager, aka Activity Monitor, on your Mac.

• Invoke  Siri  on your Mac.
• Ask,  “Siri, Open Activity Monitor.”

On a Mac, you can press the Command + Option + Escape key to open the Force Quit box, from where you can force-quit troublesome programs.

The Alt key on Mac is the Option key, and it is found on both sides of the spacebar.

Many believe a task manager in Mac is not as important as a Windows computer. Thanks to the powerful chipsets and a flawless operating system, Apple integrates into their MacBooks. But, once in a while, having a task manager becomes essential for some inevitable disruptions.

This article is an in-depth guide on Mac OS task manager- The Activity monitor. Activity monitor helps Mac users close tasks that slow down, hinder or freeze the Mac and cause it to lag and underperform.

Task manager also benefits the Mac. For example, it can close apps and change system preferences. Keep reading to find out how to correctly use the task manager on your MacBook to manage apps.

Activity Monitor – The task manager on Mac

Almost all Windows users know how a task manager works on Windows computers. It helps determine the tasks running on the computer and their effects on the computer’s performance and speed.

A task manager on Mac performs similarly to a windows task manager. Mac equivalent of a task manager is called an Activity monitor. It is a preinstalled app on Mac. Activity monitor helps regulate apps by showing how many apps are active at a time and how much energy they are consuming.

How to launch Mac task manager

There are four easy ways to open a task manager on a Mac. You can use any of these methods below to launch the Activity monitor.

• Use Spotlight search

You can open the activity monitor using Spotlight. For that, follow the steps given below:

• Press Command plus Space keys to launch the Spotlight
• Type ‘Activity monitor,’ and the app will appear highlighted; then click on it or press enter
• The activity monitor window will open

To access task manager on Mac using Finder, follow these steps:

• Click on the Finder icon from the dock
• Click on the ‘Applications’ tab appearing in the sidebar
• Then tap on ‘Utilities folder’ in the applications window
• Launch the Activity Monitor by double-clicking on the ‘Activity monitor icon’ in the utilities folder

• Add in Dock

The easiest way to launch the task manager is to add its dock icon to the main dock. To do that, follow these steps:

• Launch Activity monitor by using any of the processes mentioned above
• Right-click on the icon of ‘Activity monitor’ appearing in the dock
• Then select ‘Option’ and choose ‘Keep in dock.’
• Or, you can drag and drop the Activity monitor icon in the dock
• The above steps will add the app to the dock, and it will remain there even after quitting the application

• Use shortcut

Some versions of macOS provide a Mac task manager shortcut to launch the Activity monitor. To use this, press Command, Option, Shift and Escape keys simultaneously. Keep pressing these four keys for a few seconds until you see the Activity Monitor on screen.

Uses of task manager

Once you open the task manager, it will show you five tabs. These tabs will reveal the running applications and how they affect your Mac. You can then manage or quit all the processes obstructing the macOS from working efficiently.

You can open the task manager using all the options given below to view the apps statues:

• Check CPU usage

Showing CPU usage is the essential use of the Activity monitor. You can view all the running processes and their effect on the CPU usage and performance in the CPU tab. The CPU pane also displays the exact percentages of the power the apps are consuming and for how long they have been running.

To get information about how much CPU power an app is using, select it and then press the ‘i’ icon on the top of the screen. It will show all the information about the app. Next, press’ x’ to get rid of any app that is not in use.

A continuous process running on your Mac is called ‘kernel_task,’ which might seem like it is using many resources. However, please do not end this process; it monitors all the heavy processing applications on your Mac and tones them down to increase performance.

Sufficient RAM is the top reason for Mac’s performance. Lesser RAM means a slower Mac, but your computer will run faster if its memory is sufficient. The memory pane helps in this regard. Try stopping heavy applications to speed up your Mac quickly.

Open the ‘Memory tab’ and view the ‘RAM pressure gauge’ at the bottom. It shows the RAM available on your computer. If the bar is green, there is enough storage available, but the user needs to buy extra memory if it’s red.

Users can also decrease CPU and RAM utilization using the App tamer on the menu bar. It shows all the heavy processes running on your device and slows them down.

• Check energy use

Mac task manager also shows the energy usage of all the active apps. The Energy pane is helpful if you have not plugged your device into a charger and want to extend screen time.

Just click on the Energy pane and see all the running applications. From there, you can quit the processes and apps that use a lot of battery.

You can also check Avg energy impact. It shows how much energy an application uses on average. You can then get rid of applications that degrade battery life faster.

• Check disk activity

The Disk tab shows how apps affect your Mac’s hard drive by rewriting data. If you have mistakenly downloaded malware or corrupt application, you can view stats on this page and delete the corrupt apps quickly.

• Check network activity

Lastly, the Network pane shows how much data an app sends and receives. The network usage reveals any hidden malware or anomaly running on your Mac.

You can view all the incoming and outgoing data in the network tab and then stop the doubtful apps and delete them.

Examine processes running on Mac

You can examine all the active processes using the Mac Activity monitor. It also has a few valuable options in the menu bar. The ‘View tab’ lets you choose which applications you want to view. You can also select ‘Active processes’ to filter out which processes to consider.

Under the Windows pane of the Activity monitor, you can view the CPU and GPU performance.

If you want to know more about a particular process running on the Mac, use the steps given below:

• Open the task manager(Activity monitor) on your Mac
• Highlight the process on the Activity monitor, then click command plus ‘i’
• Or, go to ‘View’ and click ‘Inspect process.’
• An inspection screen will appear where you can view the CPU performance, RAM, and all other details

Force quit applications

Force quitting is the primary job of a task manager on Mac. You can force quit applications using the Activity monitor. It helps eliminate frozen apps or applications that take too long to process or run.

The task manager on Mac not only shows insights for the five tabs mentioned earlier but also helps to force quit applications that are unresponsive or stuck. Mentioned below are the three easy ways you can force quit applications on your Mac:

If an application is not responding and has frozen, you can use the Apple menu to force quit that process in just a few clicks.

Press and hold the ‘Shift’ key and click on the screen’s Apple icon in the top left corner. You will see the ‘Force quit’ option in the drop-down menu with the application’s name. Click on the ‘force quit’ option to remove the application running in the background.

You can also force quit applications using the dock. However, it will only be possible if the cursor is moving and you can see the dock.

Move the cursor on the top of the app that is not working. Next, select the app you want to force quit and right-click it. Finally, select ‘Force quit’ in the pop-up menu to close the app. It will stop the app’s running process immediately.

• Activity Monitor

Lastly, you can force quit an application using the macOS task manager- The Activity monitor. It will help you not only in closing an app but also show details of it. Open Activity monitor using any of the three ways mentioned above. It will list all the running applications on your Mac.

You can select any app you want to close. Then choose ‘force quit’ and confirm your choice in the dialogue box. It will close the desired application. However, do not use the Activity Monitor to force quit apps regularly. It can sometimes corrupt the apps.

If you cannot close any frozen app using the ‘x’ symbol, you can also use the keyboard shortcut. Press Command+Options+Escape to open the dialogue box of ‘Force quit applications manager.’

You can select any app in the dialogue box and press ‘Force quit’ to close it. You can quickly close otherwise unresponsive apps.

Other options

You can download the application listed below if you want to prevent apps from freezing and get a lag-free performance from your Mac.

CleanmyMac X

CleanmyMac X is an application that continuously scans your Mac and deletes apps to improve its performance. It will optimize apps and regularly delete unused data so your Mac is not overburdened. If you use this app, you will hardly need to use the task manager on Mac.

CleanmyMac X is a free software specially designed for macOS computers. It not only scans the system but also deletes and resets apps, removes the cache, and speeds up the Mac with its maintenance options.

The task manager manages the running processes on your Macbooks. It is easy to use and helps a great deal in increasing work performance. In addition, regularly using the task manager to check apps and software guarantees a better-performing computer.

In this regard, The Activity Monitor is the most helpful task manager for macOS devices. The Activity Monitor is the native task manager on Mac. Hence, it is vital to be aware of its usage. The Activity monitor window has five tabs and shows the effects of applications on Mac’s performance.

From revealing how much CPU power an application uses to the network and energy usage, the Mac task manager is easy to learn and use. This article not only discussed the uses of Apple task manager but also informed users how to use it to force quit slow applications.

What Is the Mac Task Manager Equivalent?

The Mac Task Manager equivalent is called Activity Monitor. It’s a built-in application exclusive to macOS. Despite its different name and location, the Activity Monitor serves the same purpose as the Task Manager, allowing you to oversee your system resources, including CPU, memory, energy, disk, network, and cache usage.

Activity Monitor serves as an alternative to the Windows Task Manager on Mac, functioning as a tool that reveals the amount of memory consumed by processes on your Mac and displays the currently active applications, even if they are not visibly open.

You can also use the Activity Monitor to force quit unresponsive apps when the regular methods fail. If you’re unfamiliar with this Mac Task Manager, it may initially appear overwhelming.

To help you out, I’ve covered how to use open and use the Activity Monitor on Mac in detail below.

What Is the Control-Alt-Delete Shortcut for Mac?

On a Mac, the equivalent to the Windows Control-Alt-Delete shortcut is Command ⌘ + Option ⌥ + Escape . However, this keyboard shortcut doesn’t open the Task Manager Mac equivalent, Activity Monitor. Instead it opens the Force Quit Applications window, which is like a mini version of Activity Monitor.

In the Force Quit Applications window, you can select an unresponsive application and force it to quit which is something Windows Task Manager does.

Here’s how to force quit an app using Force Quit Applications on Mac:

• Press the Command ⌘ + Option ⌥ + Escape shortcut or click the Apple icon and select Force Quit .

• The Force Quit Applications window will appear, displaying a list of currently running applications.

• Find the app you want to force quit from the list. If the application is unresponsive or frozen, its name may be highlighted in red.
• Select the application by clicking it once. Click the Force Quit button in the bottom-right corner of the window.

• A confirmation dialog will appear, asking if you want to force quit the selected application. Click Force Quit to proceed.

• The application will be forcefully terminated, closing all its associated processes.

Please note that force quitting an application may result in any unsaved data being lost, so it’s recommended to save your work before proceeding with force quitting.

Modern operating systems are not flawless. Applications sometimes crash unexpectedly, processes hang up and take up precious computing resources, and files get lost or corrupted because of bugs. Task managers are useful applications that let you monitor what’s happening on your computer and provide you with the ability to shut down misbehaving processes and file system activity for read and write events on sensitive data.

Just like Windows has a task manager, called simply Task Manager , macOS also comes with an application that provides information about computer performance and running software and allows users to terminate processes if they start misbehaving forcibly. This article introduces the official task manager in macOS, explains what it can do, and presents three alternative Mac task managers for users who would like to explore other options.

Activity Monitor Is the Task Manager for Mac

If you go to the Utilities folder under Applications on your Mac, that’s where you can find Activity Monitor, the official task manager for Mac computers. Seeing Activity Monitor for the first time can be overwhelming as the application displays a plethora of information at the same time. But once you understand what Activity Monitor does and how to use it to keep your computer running like a well-oiled machine, the initial bewilderment will be quickly replaced by an appreciation for its usefulness.

There are several tabs at the top of the Activity Monitor window: CPU, memory, energy, disk, network, and cache. Using these buttons, you can see how processes are affecting your Mac computer.

• CPU : Clicking on this button sorts running processes by the percentage of CPU capability used by each. Additionally, the percentages of CPU capability currently used by system and user processes are displayed at the bottom of the Activity Monitor window. Right next to the percentages of CPU capability currently used by system and user processes is a CPU load graph, which shows the percentage of CPU capability currently used by all system and user processes.
• Memory : Clicking on this button sorts running processes by how much memory each process uses. Displayed at the bottom of the Activity Monitor window is the Memory Pressure graph, which helps illustrate the availability of memory resources. You can change how often the graph updates by clicking on View and Update Frequency. The graph is green when enough memory resources are available, yellow when memory resources are still available but are being tasked by memory-management processes, and red when memory resources are depleted.
• Energy : Clicking on this button sorts running processes by their energy use. Displayed at the bottom of the Activity Monitor window is the Energy Impact graph. Energy Impact is a relative measure of the current energy consumption of an application, and the graph indicates how much energy is being consumed by all apps. Also displayed at the bottom of the Activity Monitor window is the current battery charge level, whose color changes from blue to green when the computer is getting power from a power adapter.
• Disk : Clicking on this button sorts running processes by the amount of data they read from your disk and written to your disk. After clicking at the Disk button, the bottom of the Activity Window displays a graph that shows total disk activity across all processes. The graph has two lines: one blue and one red. The blue line shows either the number of reads per second or the amount of data read per second, while the red line shows either the number of writes out per second or the amount of data written per second.
• Network : Clicking on this button sorts running processes by how much data they are sending or receiving over your network. After clicking at the Network button, the bottom of the Activity Monitor window displays a graph that shows total network activity across all apps. The graph has two lines: one shows either the number of packets received per second or the amount of data received per second, and the other one shows either the number of packets sent per second or the amount of data sent per second.
• Cache : Available only in macOS High Sierra 10.13.4 or later, the Cache button shows how much cached content local networked devices have uploaded, downloaded, or dropped. After clicking on the Cache button, the bottom of the Activity Window displays a graph that shows total caching activity over time.

3 Ways on How to Open Task Manager on Mac

There are several ways how you can open Activity Monitor, some more convenient than others:

Way 1: Finder

• Open Finder.
• Go to Applications and then Utilities.
• Click on Activity Monitor.

Way 2:  Spotlight

• Press Command-Space bar to open Spotlight. 📍 You can also click in the upper-right corner of the menu bar.
• Start typing “Activity Monitor.”
• Press enter once Activity Monitor becomes highlighted.

Way 3: Dock

• Open Finder and navigate to applications and then Utilities.
• Drag the Activity Monitor application icon to the dock to pin it.
• Once pinned, you can instantly start up Activity Monitor simply by clicking on the pinned icon in the dock.

How to Use Mac Task Manager

To use Mac’s task manager, Activity Monitor, to stop a process, simply select the process you want to stop from the main application window and click on the stop button located in the top-left corner of the window.  

What Is kernel_task Mac?

After playing with Activity Monitor for a while, many people discover that one particular process, called kernel_task, is taking up a lot of system resources and start wondering whether it’s possible to kill it.

Because kernel_task is essentially the core of the macOS operating system, it’s impossible to stop it without making the entire system unusable.

According to Apple , “one of the functions of kernel_task is to help manage CPU temperature by making the CPU less available to processes that are using it intensely”. Sometimes, an application stops behaving as it should and enters into an endless loop, consuming system resources without doing anything useful. The kernel_task process then often steps in and enters into a similar looped state, unable to tame the application that has gone wild. Typically, the only solution is to restart the computer and avoid the problematic application.

Best Mac Task Manager Alternatives

Being the official task manager for Mac computers, Activity Monitor is tightly integrated with the macOS operating system and has all the features needed to manage tasks. Despite its first-class status, there are a few mac OS task managers worth having installed on your computer for those occasions when Activity Monitor isn’t enough to accomplish everything you want to do.

iStat Menus

iStat Menus is an advanced Mac task manager with notifications based on CPU, network, disk, battery, weather, and other events, support for hotkeys, reorderable drop-down menus, a compact notification center widget, and many more other options. We love how iStat Menus can reside entirely in the menubar and display essential information at a glance. A single license costs $18.14 for new users and $12.09 for users coming from an older version.

BitBar is an extremely versatile addon for the menu bar that can display all sorts of useful information, including battery health, CPU temperature, CPU load, disk usage, CPU usage, power status, and much, much more. BitBar also supports plugins, and many developers already contributed an impressive number of plugins to BitBar’s plugin repository. If you have the skills and are willing to contribute, you can create your own plugin for BitBar and submit it to be included with other plugins on BitBar’s official website.

XRG is an open source system monitor for macOS. Just like Activity Monitor, XRG allows you to monitor CPU activity, memory usage, battery status, network activity, and disk usage. Besides these, XRG also makes it possible to display stock market data, current weather, and more. It’s lightweight, easy to use, and works with all recent versions of macOS.

Bonus: Disk Drill

Applications don’t like when they are shut down suddenly using Activity Monitor or any other task manager. In some cases, you may even experience data corruption or data loss. Unfortunately, task managers can’t help you recover your lost or corrupted data. For that, you need a data recovery application such as Disk Drill. With it, you can quickly and painlessly recover virtually any file format, including images , videos, documents , and others.

Besides data recovery, Disk Drill can also help you keep your hard drive nice and tidy as it comes with several useful disk tools. For example, Duplicate Finder can help you find duplicate files, Mac Cleanup can tell you which files take too much space on your drive, and data backup makes it possible to create byte-to-byte disk and partition backups. You can download Disk Drill for free from its official website.

Task Manager, which goes by the name of Activity Monitor on Mac OS X, is an application that allows you to view and monitor all active processes running on your computer. If your computer is running slow or inefficiently, you can open Activity Monitor to determine which applications are consuming the highest amount of resources. Activity Monitor is stored in the Utilities folder on Mac OS X.

Quick Steps

• Click on Applications > Utilities .
• Select Activity Monitor .
• Click through the various tabs to view how your computer's resources are being used.

Opening Activity Monitor

Using Activity Monitor

• Select the option to “Force Quit” any processes that are unresponsive or won’t close after selecting “Quit.” Applications that are looping, unresponsive, or taking an excessive amount of time to load may need to be closed using the “Force Quit” option.

• If there is little to no memory next to “Free,” or any values displayed next to “Swap Used,” you may want to consider purchasing more RAM for your computer. These signs indicate that your computer is out of physical memory and is using a portion of the hard drive for temporary storage -- leading to longer wait times.

Expert Q&A

• If you suspect malware has infected your computer, look for and quit any unfamiliar processes running in Activity Monitor. In many cases, malware will run as a background process and significantly slow down your computer. [3] X Research source Thanks Helpful 0 Not Helpful 0
• If you notice that one or more applications continue to run automatically in the background, launch those programs, then search for options in their Settings menus that allow you to prevent the applications from launching upon startup. Sometimes, third-party applications will launch automatically by default when you start your computer, and run continuously in the background without your knowledge. Thanks Helpful 0 Not Helpful 0

Control Alt Delete on a Mac - How to Open Task Manager on your Macbook

It happens to the best of us: we're working away on some important project, and our trusty computer freezes. Or rather, a program we're in just stops responding. So what do you do?

If you have a Windows machine, you can just use the familiar CTRL+ALT+DEL sequence to force quit whatever program is misbehaving. But that doesn't work on a Mac.

Don't worry, though - there is one super simple way to force quit on a Mac (and a couple other methods you can keep in your back pocket as well). Let's learn what that is.

How to force quit on a Mac

The easiest way to force a program to quit on your Mac is a simple key sequence similar to ctrl+alt+delete. Just tap COMMAND+OPTION+ESC, in that order. Here's where those keys are located on a typical Mac keyboard:

This will bring up a task manager type window that looks like this:

Then just select the non-responsive program and hit "Force Quit" which will stop that program from running.

Note : since you'll be forcing that program to quit in the middle of whatever you were doing, any unsaved data might be lost. Make sure you enable auto-saving, back up your projects often, and keep your computer clean and up to date.

An alternative method

Why learn just one way to force quit when you can learn two? Click the Apple logo at the top left of your screen in the menu bar. Scroll down to "Force Quit" and it'll bring up the same task manager.

Simple as that!

Now that you've dealt with your crashing application, you can get back to work. :)

How to Use Task Manager macOS and Activity Monitor

Before I started using a Macbook, I was always a Windows user. Making the change wasn’t easy, as many things are different on the macOS X system than any Windows I’ve seen before. Don't be afraid if you’re in the same shoes as I was. Everything you know and love from Windows can be found on a Mac under a different name.

One frequent thing new Mac users seem to look for is the Task Manager . It’s a useful tool on Windows that allows you to see a plethora of information at once. With the Task Manager, you can force quit apps (known as the “End Task” option on Windows) and see various consumption details.

Coming from Windows , I know that the Task Manager is an essential tool to identify issues or force quit apps. It’s almost a knee-jerk reaction to open it as soon as you suspect something is wrong. However, the classic “ Ctrl-Alt-Del ” shortcut doesn’t work on a Mac. Trust me, I tried.

On macOS X, this tool is called the Activity Monitor . It delivers on the same premise but operates in a slightly different way. If you’re lost and want to know where to find this tool and how to use it on Mac, this article is here to help.

Summary: Task Manager MacOS

The Mac Task Manager is a mini-version of the Activity Monitor. To open it,  simultaneously press down the [CMD] + [ALT] + [ESC] keys on your keyboard . This will open a window containing a list of all currently opened programs and applications that are running in the background.

What is Activity Monitor in Mac?

Activity Monitor in Mac is basically the equivalent of Windows Task Manager. This utility shows how much memory your Mac processes are using and which apps are currently active (even if they aren't open), letting you force quit stalled ones if you can't close them the usual way. If you've never used the task manager in Mac before, it can be quite a lot to take in.

How to open the Task Manager on Mac - Task Manager macOS

Most Windows users know you can quickly fire up the Task Manager by right-clicking on the taskbar. This feature is missing from Mac, as right-clicking on the Dock only brings up some settings. 

So, how exactly do you open the Activity Monitor — the Mac equivalent of the Task Manager — if there’s no shortcut or Dock option? 

Launching Activity Monitor (Task Manager Mac) is still quite simple. Pick one of the three ways to do it:

Open Activity Monitor from Spotlight:

• Press Command + Space to open Spotlight
• Start typing Activity Monitor
• Once Activity Monitor comes up highlighted, hit Enter or click on it.

Open Activity Monitor from Finder:

• Go to your Launchpad (the rocket icon in your Dock) or Click on Finder in your Dock.

• Double-click on the Activity Monitor icon.

Open Activity Monitor from Dock:

If you're having recurring troubles, setting up Activity Monitor in your Dock is something worth doing. It's essentially a handy one-click Mac Task Manager shortcut. But before you can open Activity Monitor from your Dock, you must first use one of the previous two methods. Then, once Activity Monitor is active:

• Right-click on the Activity Monitor icon in your Dock.
• Select Options.

• You can launch Task Manager mac like any other program.

What is the Control-Alt-Delete shortcut for Mac?

Sadly, there’s no direct shortcut to open the Task Manager on a Mac. However, you can use a shortcut to force quit applications, which is one of the things the Task Manager in Windows is capable of.

Press the ⌘-Option-Esc shortcut on your Mac to bring up the Force Quit utility. Here, simply select the app you want to close and click on the blue button in the corner. If an application is frozen and not responding, its name will be highlighted in red.

How to use Activity Monitor on a Mac - How to use Mac Task Manager

If you decide to use Activity Monitor as your task manager on Mac, you should learn how to work with its monitor indicators.

When you open the Activity Monitor, you’ll be able to see all of the applications currently running on your Mac. The apps and processes appear even if running in the background, making it easy to spot unusual activity.

Task Manager mac - CPU usage

By default, the Activity Monitor opens on the CPU tab. This means you can see what’s consuming the most of your Mac's CPU power. It also shows you the exact percentages of power they are consuming and how long each app has been running.

You can sort all processes in Activity Monitor by CPU usage, from highest to lowest, by choosing View > All Processes and clicking on the %CPU column.

You might notice a process in the CPU tab called "kernel_task" that could take a large share of resources. Don't panic, and don't shut it down! The process simply ensures your CPU isn't working too hard by forcing other memory-intensive Mac processes out. As a result, it might seem like one of the heaviest processes on the list. Similarly, "mds" and "mdworker" help index files for the Spotlight search, which sometimes spikes their appetite.

Task Manager mac - Check RAM usage

Switching to the Memory tab (the second tab) in the Activity Monitor, you can see the amount of RAM each process consumes. RAM is directly responsible for the speed of your Mac, so getting rid of heavy users is the fastest way to speed things up. Like Windows, you need to pay attention to having enough RAM for your computer to function properly. If too much of your memory is taken up, you’ll notice that your system is slow and a pain to operate. Make sure to close out apps with high RAM consumption to avoid this.

Another interesting feature you can see in the Memory tab is the RAM Pressure Gauge at the bottom. If the bar is green, then your Mac's RAM isn't being taxed too much. But if it turns red — consider buying additional memory for your machine.

Tip: You can decrease CPU and RAM consumption by apps through the App Tamer, a menu bar utility that spots heavy consumers on your Mac and slows them down automatically.

Check for energy use in macOS task manager

The Energy tab helps you reduce battery usage by monitoring what applications are consuming your battery. Use this tab when your MacBook is unplugged to extend your battery life until you can plug back in.

Tip: check Avg Energy Impact — this will tell you which apps consume the most energy on average. If you don’t use those apps often, consider getting rid of them.

Disk activity on a Mac Task Manager

While the Disk tab is not as useful daily as the others, it’s still a crucial part of the Activity Monitor. Here’s where you can find all processes interacting with your hard drive and rewriting data. If you get a malware infection, you’ll be able to spot and quit the harmful processes here.

Network activity on a Mac Task Manager

The last tab in the Activity Monitor is the Network tab. It displays all the data sent and received by the apps you’re currently using. I personally use this tab to spot any outliers sending large amounts of data when I’m using my Mac to browse or work online.

Inspect processes in Mac Activity Monitor

If you want to go deeper into a specific process running on your Mac, highlight the process in Activity Monitor and press Command + I. Alternatively, to see the process go to View > Inspect Process. On the inspection screen, you’ll find information about how much CPU and memory this process uses, how long it runs, and more.

How to see your system status in the Dock with the Activity Monitor

You might think that it’s a hassle to constantly have to keep searching for the Activity Monitor to see the status of your Mac. I thought the same too, which is how I found out that there’s a much easier way.

Keep an eye on your system status right from your Dock by utilizing the live update feature of the Activity Monitor. Simply open the Activity Monitor and expand the View tab in the top-bar of your Mac. Here, hover over the Dock icon and select the desired update you want to see.

After choosing the option you wish to display, you’ll immediately see the Activity Monitor change to a live update.

5. Save MacBook battery power with Activity Monitor

When apps and other processes use a lot of power, they slow down your Mac and use more energy. If you’re using a MacBook on battery, that could limit how long you’re able to work away from an electricity outlet. Thankfully, you can use Activity Monitor to save some energy on your Mac .

Use these steps to check for energy use in Activity Monitor:

• Open Activity Monitor and go into the Energy tab.
• Look at the Energy Impact tab to see how much power each app is using.
• Use the 12 hr Power tab to see how much energy was spent in the past 12 hours.
• Quit apps that are using a lot of energy.

6. Use Activity Monitor to limit internet use

Most internet providers don’t limit how much you can download in a month anymore, but there are still good reasons to limit network activity on your Mac. Activity Monitor is a great way to keep tabs on which processes are sending and receiving data over the network.

To check what’s being downloaded and uploaded by your Mac:

• After opening Activity Monitor, select the Network tab.
• Click the top of the Sent Bytes column to sort highest to lowest. Note any large and unexpected figures.
• Do the same with the Rcvd Bytes column.
• Kill any apps using a lot of bandwidth.
• If you don’t recognize something, search for its name on the web to find out if it’s malware, then run an antivirus scan if necessary.

7. Other handy ways to use Activity Monitor

These are the key ways to use Activity Monitor on your Mac, but there are other useful things you can do, such as:

• See real-time CPU, network, and disk usage in your Dock .
• Track memory usage with the help of the memory pressure chart to see if you need more RAM. Note that you can’t change the RAM in all computers.

If your goal is to speed up your iMac or laptop, regularly reduce system storage and remove cache files to ensure you have plenty of free space, which will keep things running smoothly.

• Remember, Activity Monitor tells you what’s happening on your Mac

Activity Monitor is a useful utility that gives you insight on what’s going on with your Mac. It’s particularly helpful when you want to find out what’s slowing down your machine, force quit frozen apps, and when you’re worried you have a malware infection.

How to Open Task Manager on Your MacBook

Many users who have switched from Windows computers to Mac often wonder  how to access Task Manager on Mac . The equivalent of Task Manager in Mac OS is called the Activity Monitor. It lets you control system settings, view information about Mac apps or processes, and even manage apps easily. Let’s find out how to open and use Activity Monitor.

Table of Contents

Users situation.

I have bought a new MacBook but have a confusion about how to open the task manager in mac. I am new to this so please help!

How to Open the Task Manager on Your Mac

To open the Task Manager on Windows, all you need is just right-click on the taskbar. When it comes to how to start Task Manager on Mac, the process is different. Below you will find several variants:

• Go to the Launchpad and enter “Activity Monitor” in the search box. Click on the “Activity Monitor” icon.

2. Use the Spotlight search. Just press the Command + Space key combination, type “Activity Monitor” in a search engine and press “Enter” to open the application. Instead of using a keyboard shortcut, you can also click the magnifying glass in the upper right corner of the screen to display the search engine.

3. Navigate “Applications” and select the “Utilities” folder. Here find the “Activity Monitor” and double-click it.

Like many other applications installed on Mac, there are several ways to open Activity Monitor and it is all up to you: to choose the only one (the most convenient to you at any time) or use several of them according to your wishes.

Alternative Way to Use Task Manager MacBook

Activity Monitor is not the exact copy of the Windows analog and it lacks some features. That is why if you want to monitor the running processes a little more closely and get real-time updates on your Mac’s performance we can recommend you an excellent Mac Task Manager alternative –  Commander One .

The app allows viewing and managing all the running processes on your Mac computer and if it is required to kill the process simply by pressing the Del button. Among the advantages of this app is the alphabetic order of all running processes with detailed information about them (the process name, PID, used memory, the date and the time of launch, etc.), the ability to kill even the system processes.

Besides that, Commander One is a powerful file manager that helps you to have well-organized documentation on your Mac with a huge variety of handy features (Terminal emulator, cloud storage integration, mounting and managing iOS, Android, and other devices supporting MPT protocol, root access, archiver, etc.).

Terminating Stubborn Programs with "Force Quit"

If you have used computers running Windows, then you know that the Ctrl+Alt+Delete is used for terminating unresponsive programs. There is a similar keyboard shortcut on the Mac as well.

1. When a program stops responding, launch the “Force Quit Applications” dialog box by pressing Command + Option + Esc.

2. Once done, you’ll see a list of currently running applications.

3. Choose the unresponsive app from the list and click the “Force Quit” button.

4. A pop-up window will appear asking if you are sure. After confirmation, the app will be closed.

How to See Your System Status in the Dock with the Activity Monitor

Activity Monitor lets you view detailed information about the processes running on your Mac and how they affect CPU, memory, energy, disk, and network. What’s more, you can monitor the status of your system right in the Dock.

• Open the Activity Monitor.

2. Go to the Dock and right-click on the “Activity Monitor” icon.

3. In the pop-menu, hover over the “Dock icon”.

4. Choose one of the options and the Activity Monitor icon will change to the real-time update.

Mac Activity Monitor and CPU Load

The Activity Monitor is divided into several categories: CPU, Memory, Energy, Disk, Network, and Cache. They are the main indicators of system monitoring and also provide valuable information for troubleshooting. Each pane shows real-time statistics and resource usage graphs.

By default, Activity Monitor opens in the CPU tab that shows how each process uses the CPU on your computer. These statistics will help you determine which processes are affecting your Mac’s performance, battery life, temperature, and fan activity. At the bottom, you will find the following information:

• System.  Percentage of the total CPU time the process is using (% CPU).
• User.  The percentage of current CPU usage. This usage applies to applications that the user have opened.
• Idle.  The percentage of time that the CPU is idle, not performing any tasks.
• CPU Load.  CPU usage over time.
• Threads.  The total number of threads used by all processes.
• Processes.  The total number of processes.

Please note that when you open the Activity Monitor, the CPU usage for the kernel_task process is quite high. Also, the fan may work harder than usual. In simple terms, kernel_task regulates the load on the central processor, preventing the system from overheating.

Memory Pane

In the Memory pane of the Mac Activity Monitor, you can find out how much RAW your Mac is using, find a real-time memory graph with values. These stats will help you diagnose performance, and check the used memory, wired memory, application memory, etc.

• Memory Pressure.  Here you will see the availability of memory resources highlighted in different colors.
• Physical Memory.  The amount of your Mac’s RAM.
• Memory Used.  The total amount of memory currently used.
• App Memory.  The total amount of memory currently used by all applications and their processes.
• Wired Memory.  Memory that cannot be paged out.
• Compressed.  The amount of memory that is compressed to make room for other processes.
• Swap Used.  The total amount of memory used on the startup drive by macOS memory management.
• Cached Files.  Memory that was recently used by applications and is now available for use by other applications.

Energy Pane

The Energy tab shows the total energy use, as well as provides information on how much energy each app consumes. Let’s check each parameter of the Energy pane.

• Energy Impact.  The total energy used by all applications.
• Graphics Card.  The type of graphics card being used.
• Remaining Charge.  Percentage of remaining battery life.
• Time Until Full.  The amount of time the Mac must be plugged into the power source before it is fully charged.
• Time Remaining.  Estimated time that a Mac can run on battery power.
• Time on Battery.  The time elapsed since the device was unplugged from the power source.
• Battery.  Battery level for the last 12 hours.

The Disk panel shows the amount of data each process has written to and read from your disk. It represents the number of times your Mac has accessed the disk to read and write data.

Network Pane

The Network tab displays the data your Mac is sending or receiving over the network. You can also quickly identify the applications that are transferring data and external resources for each process in the Task Manager. The information at the bottom of the Network pane shows the overall network activity of all applications.

If your MacBook is running macOS High Sierra 10.13.4 or later and the content caching is enabled, you’ll also see an additional pane – Cache. Here you will find information such as the amount of cached content uploaded, downloaded, or dropped over time by local network devices.

It is very important to know how to use the MacBook Task Manager. Activity Manager not only stops slow or unresponsive processes but also contains useful data and statistics to help you check and improve your Mac’s performance.

What Is Activity Monitor? The Mac Equivalent of Task Manager

Learn all about Activity Monitor on your Mac and how to use it to check detailed information about your system.

Activity Monitor is the Mac equivalent to the Windows Task Manager. It displays a variety of resources in use on your system in real time. These include processes, disk activity, memory usage, and more to provide a sort of dashboard into what’s going on in your Mac.

We’ll show you how to read and use Activity Monitor for Mac. You’ll also learn how CPU, RAM, and disk activity can affect your Mac’s performance over time.

How to Open Activity Monitor on a Mac

The Activity Monitor app lives in Applications > Utilities . To open it, press Cmd + Space to launch Spotlight. Then type in the first few letters of the app and press Return when Activity Monitor appears at the top of the list. However, there are various other ways to open and interact with the Mac resource monitor. Here’s our guide on opening the task manager on a Mac .

In the Activity Monitor, there are five system monitor indicators that give you the real-time stats and graphs of resource usage over time. The data might be useful to troubleshoot problems on your Mac. We’ll detail each of these options below.

1. Monitor the CPU With Activity Monitor

The CPU tab shows how every process uses your computer’s processor. You’ll see what percentage of the total CPU a process is using ( % CPU ), how long it’s been active ( CPU Time ), the number of times a process awoke from the sleep state ( Idle Wake Ups ), and more.

At the bottom of the screen, you’ll also see the percentage and graph of your CPU used by the System (red) and User (blue).

List Processes by %CPU

To see which processes are consuming excessive resources, choose View > All Processes and click on the % CPU column to sort them by usage. Some processes may occasionally display high CPU usage, but that doesn’t necessarily indicate a problem. For example:

• The mds and mdworker processes associated with Spotlight might show frequent CPU spikes during indexing. This is perfectly normal for a new or recently formatted Mac. The process will end automatically when done.
• The kernel_task process manages your Mac’s temperature by limiting CPU access to processes that use the CPU intensely. It’s common to see this consume more CPU over time. Thankfully, you can fix “kernel_task” high CPU usage on your Mac .
• A web browser may show high CPU usage while rendering too many tabs or displaying multimedia content like video.
• Cloudd is the daemon process that deals with syncing iCloud data. If you see a spike in CPU usage, this doesn’t indicate a problem. Once the syncing completes, the %CPU should get reduced.

View CPU Usage and History

Click the Window menu to open CPU Usage , CPU History , and GPU History in a separate window. The information will give you insights into your overall CPU utilization. The CPU History window shows user and system load on each core over time.

Quit Rogue Processes

If an app is acting weird, becomes unresponsive, or crashes, then your best option is to force quit it. You’ll see the problematic processes in red text with the phrase Not Responding .

To terminate the process, select the app and choose View > Quit Process. Or click the X button at the top of the toolbar to quit the process.

If Activity Monitor is not working, try these alternative steps:

• Press and hold Cmd + Option + Esc . Choose the app you want to quit in the Force Quit Applications dialog box and click Force Quit .
• Type the following command: >ps -ax
• Press Return to list all the running process along with PID (Process Identification) number. To force quit an app, type >kill < PID   number >

You should never force quit system processes or ignore processes that run as root . Instead, find out the probable cause by looking at logs or restart your Mac.

2. The Memory Tab in Activity Monitor

The Memory tab displays how much RAM your Mac is using. Along with the CPU, it’s a chief performance indicator of your Mac. At the bottom of the window, you’ll see a real-time memory graph with values that can help you diagnose performance issues.

The Memory Used value is the total amount of memory used by all apps and system processes. It’s divided into the following:

• Wired Memory: Processes that must stay in memory. They can’t be compressed or paged out.
• App Memory: Memory allocated to all app processes.
• Compressed: macOS includes software-based memory compression to increase performance and reduce energy use. Your Mac compresses the content used by less active processes to free up space for more active ones.

Check if Your Mac Needs More RAM

The Memory Pressure graph shows the present state of memory resource usage through different colors. Green means sufficient memory resources are available, while Red means your Mac has run out of memory and needs more RAM to operate efficiently.

The borderline Yellow is a warning sign. Check to see if an app is using up memory and causing the memory pressure to increase. If that’s the case, quit the app.

View Cached Files Memory Usage

Cached Files is another useful parameter. This tells you how much memory is presently used by apps, but is still available for other apps to take. For example, if you quit Apple Mail after using it for a while, its data will become part of the memory used by cached files.

If you re-launch the Mail app, it’ll launch faster. But if another app needs RAM, macOS will dynamically remove cached data and allocate it to other apps.

If Cached Files is consuming a lot of memory, don’t fret about it. As long as memory pressure is green, it shouldn’t be a concern. You might need more RAM in the future but, before that, check out some common mistakes that slow down your Mac . Since Apple silicon Macs have an integrated system on a chip, your only option is to quit the app.

The Swap Used and Compression Entries

These two parameters tell you how much active process data was swapped out to the startup drive or compressed to save space. Compression is preferred to swapping because it makes more room for memory and doesn’t slow down your Mac.

A low number for Swap Used is acceptable, but a high number indicates that your Mac doesn’t have enough real memory to meet the application demands.

Catching App Memory Leaks

Memory leaks happen when an app doesn’t release the allocated memory for reuse. Over time, the leak accumulates and the problematic app comes to a grinding halt. You can easily identify these leaks through Activity Monitor.

3. Review Energy Usage With Activity Monitor

Every MacBook user is likely to have a valid concern about battery life; you probably want your laptop to run for as long as possible. The Energy pane of Activity Monitor is your Mac’s resource monitor. It shows overall energy use and power used by each app.

You’ll see the Energy Impact of running apps, along with the Avg Energy Impact of each app over the last 12 hours or since your Mac booted up, whichever is shorter. The App Nap feature allows your Mac to put inactive apps to sleep. This field tells you which apps support this and whether it is preventing your Mac from going to sleep or not.

Implications of Energy Usage

The more energy a particular app uses, the shorter your battery life becomes. You should check the Avg Energy Impact column to see which apps use the most energy over time. Quit those apps if you don’t need them.

For web browsers, you don’t have to quit the entire app. Click the triangle next to the browser to expand the list of child processes. Find the one with the highest energy impact, then force-quit that process.

Generally, those are tabs or plugins that consume significant energy. If you’re using Chrome, check out how to control Chrome’s memory usage and free up RAM .

4. Activity Monitor’s Disk Panel

The Disk pane shows the amount of data each process has read from or written to the disk. It denotes the number of times your Mac accessed the drive to read ( read IO ) and write ( write IO ) data. Blue shows the number of reads per second while red indicates the number of writes per second.

Implications of Disk Activity

Having enough RAM is essential for performance, but free space on your startup drive is critical for system stability. Pay close attention to the number of reads or writes and observe how your system accesses the read or write data.

If disk activity is high, does it correlate with the CPU usage? Some apps or processes can cause both heavy disk activity and CPU usage, like when you convert video or edit RAW photos. And if your Mac is short on RAM, you’ll see frequent spikes in disk activity due to swapping.

5. Using the Network Tab in Activity Monitor

The Network pane shows how much data your Mac is sending or receiving over your network. At the bottom, you’ll see network usage in packets and the amount transferred (in red) and received (in blue).

Implications of Network Activity

Some processes naturally generate a lot of network activity, but others using the network a lot might not make much sense. Determining which external resource each process is connecting to is a huge pain.

If you’re curious to see what data packets are passing through which processes, use the Little Snitch app to monitor network traffic on a per-app basis.

Generate a System Diagnostics Report

Activity Monitor can also help you generate a report about the status of your Mac. You can save the report and send it to a friend or Apple support for troubleshooting purposes.

To do this, choose View > System Diagnostics . You may need to wait a while for this to complete.

Tune Up Your Mac for the Best Performance

Activity Monitor is the stock macOS task manager. By running this tool and following the advice we’ve covered here, you can work out why your Mac is slow and what each parameter means to your overall system health.

Once you catch the source of the problem, try some tips to tune-up your Mac and make it run faster and smoother.

What is Task Manager on Mac

Activity Monitor is the Task Manager for Mac and it functions in a very similar way as it does in Windows. This macOS utility gives you a general overview of what your MacBook is doing.

This Mac Task Manager monitors Mac activity in real-time such as processor load, active processes, running applications, and the amount of memory being used. Besides, you can use the Mac Task Manager equivalent to forcibly quit any sluggish programs or non-responsive programs running in the background to  free up memory on a Mac  or  fix your frozen Mac .

How to work with Mac Task Manager

When Activity Monitor is opened successfully, you'll see the below window with apparent 5 tabs.

CPU : List all the processes that are currently taking up your Mac's CPU, and demonstrate how long they have been running.

Memory : Reflecting how much  RAM  every process is taking up. RAM is directly responsible for the speed of your Mac, so getting rid of heavy users is the fastest way to speed things up.

Energy : Indicating apps and processes that drain your battery and the energy used by each app or program.

How to open Task Manager on Mac

If you have recently switched from Windows to Mac, you may find that most Windows keyboard shortcuts don’t work on a Mac. While navigating the Mac operating system does have its own method, most users find it intuitive and quick to learn.

The most frequently asked questions from new Mac users include:

• What is Control Alt Delete on a Mac?
• How to get Task Manager on a Mac?
• How to force quit on a Mac, and so on.

In this blog post, we will explain the Mac equivalent of the Windows Task Manager and how to view running processes in macOS.

1. What is the Control Alt Delete for Mac. 2. How to open Mac Task Manager. 3. How to see what programs are running on a Mac. 4. How to use Activity Monitor on a Mac. 5. How to force quit on a Mac. 6. How to monitor memory usage with Memory Cleaner. 7. Frequently asked questions about memory usage on a Mac.

1. What is the Control Alt Delete shortcode for Mac

Control-Alt-Delete is a shortcut to call the Force Quit command for programs on Windows. For the macOS system, you should use the Command-Option-Escape shortcut to call the Force Quit Applications window.

Also, you can get this window by clicking the Apple icon in the Menu bar and selecting Force Quit .

2. How to open Task Manager on a Mac

When an application freezes on Windows, the Ctrl-Shift-Esc command is used to bring up the Task Manager and quit the process in question. But how about on a Mac? How do you end processes that crash Safari or lock the machine up?

First, we would like to mention that the Mac equivalent of Task Manager is called Activity Monitor. Just remember that Apple Task Manager = Activity Monitor .

Use one of these two ways to open Activity Monitor on a Mac:

3. How to see which programs are running on your Mac

1. Use Activity Monitor

With Activity Monitor, you can monitor many parameters of the system, such as:

• Energy used
• Network monitoring

2. Use Terminal* to view a list of running processes.

For those who prefer working with Terminal, there are simple commands to view the list of running programs. Just open the Terminal and type only one word:

If you need to view a list of the most voracious applications that consume the most bytes, sort them by CPU:

Sort applications by memory usage:

top -p size

*For more tips like this, see our previous article Top 8 most useful Terminal Commands.

4. How to use Activity Monitor on a Mac

Now let’s take a closer look at each parameter of open programs on a Mac. With help from Activity Monitor, we will identify the programs and processes that are consuming too much of your system’s resources.

How to check CPU usage on a Mac

If your Mac starts working too slowly, it overheats , the fans work continuously and make noise, and programs may freeze. Most likely there are some programs that are consuming a large portion of processor load. You can identify such programs with the help of Activity Monitor.

In this case, launch Activity Monitor and go to the CPU tab . Sort the list of programs by CPU column, find out the programs that use most CPU, and close such programs.

How to check RAM usage on a Mac

If your computer is running slowly, there are several indicators that your Mac’s performance is due to limited RAM. One example is when programs work slowly and documents even open slowly, but without overheating or the fans making noise. In this case, there is most likely not enough free RAM on your Mac for your programs to function properly. To create more free space, find the programs that use the most memory and close unused ones.

In the Activity Monitor app, go to the Memory tab to see memory intensive Mac processes.

How to find apps that are using and draining the most battery life

If your Macbook’s battery is draining very quickly, we recommend checking the programs which are using the most energy. To get this information, switch to the Energy tab within Activity Monitor . Here you can find the data relating to how apps use your Macbook’s battery. Find the apps that are using the most energy, and if you don’t need them at the moment, close them.

How to check Disk activity on a Mac

Most users don’t need to worry about the Disk tab . This part of Activity Monitor allows users to troubleshoot or monitor real-time disk activity. Here you can check how much data is being written to and read from your Mac’s drive by different processes, as well as the number of times that your Mac accesses the disk.

How to check Network activity on a Mac

If you are having internet problems, if some network accounts are unavailable, or if network connections fail often, then you should check Network activity on your Mac. Go to Activity Monitor’s Network tab to see how much bandwidth the processes are using. Then sort the programs by “sent Bytes” or “Read Bytes” to see the most active processes. Finally, close unneeded active programs.

5. How to force quit on a Mac

Whenever any application crashes on your Mac or it doesn’t respond for a while, you may need to force quit it. Here are several ways to do that:

1. Use the Dock panel.

Click the app’s icon in a Dock panel, hold the Option key and select Force Quit command.

2. Use the “Force Quit” dialogue.

What to do when the Dock won’t pop up? A list of open programs can be also viewed via a “Force Quit” dialogue. There are two ways to open the “Force Quit” dialogue:

• Use the simple keyboard shortcut Command + Option + Escape.
• Or go to the System Menu → select Force Quit command.

Then select the app you want to stop and click on Force Quit.

6. How to monitor memory usage with Memory Cleaner

In the previous paragraphs, we showed several ways to force close apps on a Mac in order to find out what apps are running. Now we would like to share an easy way to complete all these tasks and speed up your Mac in just one click. Simply use the free utility, Memory Cleaner .

Memory Cleaner can display the list of apps that use the most memory on your Mac, clear inactive RAM memory with just one click, and stop all running applications. With the app, you can get access to memory usage directly from the menu bar.

As you can see, there are various equivalents of macOS Task Manager, and Activity Monitor is one of them. It is a built-in utility that is used by most Mac users. However, if you want to monitor RAM memory usage and clear inactive RAM, we would recommend using the free Memory Cleaner app.

Frequently asked questions about memory usage on a Mac

The equivalent of Windows Task Manager on a Mac is the Activity Monitor application. Activity Monitor is the default Apple application, which you can easily find in Launchpad.

Activity Monitor displays open programs on your Mac, as well as detailed information about them, including CPU usage, memory usage, disk usage, network usage, and energy impact. With Activity Monitor you can manage working processes and quit tasks or apps.

Activity Monitor allows you to terminate all the processes and applications running on your system. But since most of the processes are system ones, we do not recommend selecting all the processes and click to force close them all at once. Closing some system processes may prevent your Mac from functioning.

Select an app you want to terminate, and then use the Stop button on the toolbar.

Follow these steps to find malware using Activity Monitor:

• Quit all your network-related apps (web browsers, iTunes, email clients and so on).
• Disable Bluetooth.
• Disable all the options in the System Preferences → Sharing section.
• In Activity Monitor, go to the Network tab.
• Check whether there is unexpected network activity on your Mac.

In the Activity Monitor app, go to the CPU tab. Check which apps are using too much of the CPU’s resources. Select those apps and click the Stop button (X icon on the top).

How to install ChromeOS on your old PC or Mac

D o you have a sluggish laptop that no longer receives Windows or macOS updates? Before disposing of it, breathe new life into it with ChromeOS Flex, a version of ChromeOS that runs on older PCs and Windows and Mac laptops. With ChromeOS Flex, you can enjoy the key features of the best Chromebooks without spending too much.

What is ChromeOS Flex?

Google acquired the company behind CloudReady in 2020. CloudReady allowed installing ChromeOS on non-certified devices. Building on its acquisition, Google announced ChromeOS Flex in 2022, a successor to CloudReady, to make old Windows laptops and MacBooks usable again.

ChromeOS Flex is free to download and use. It is primarily meant for older PCs, laptops, and MacBooks used by businesses and schools that are now too slow to run Windows or macOS properly. The OS promises faster boot times, a reliable experience, background updates, and more. Google aims to reduce e-waste and extend the lifespan of old PCs with ChromeOS Flex.

How do ChromeOS and ChromeOS Flex differ?

ChromeOS and ChromeOS Flex share the same foundation. However, there are a few differences that you should be mindful of before you install ChromeOS Flex on your old laptop.

ChromeOS only runs on certified hardware. ChromeOS Flex runs on a range of older hardware. Chromebooks also benefit from Google's Titan C security chip and provide a verified boot to prevent tampering with system files.

Since older PCs do not have a Trusted Platform Module (TPM) , ChromeOS Flex cannot provide hardware-level encryption. The data is encrypted, but the encryption keys are not protected at a hardware level. This means it's possible to bypass this encryption with the right set of tools. Google supports TPM encryption in laptops and PCs certified by it on ChromeOS Flex.

ChromeOS Flex doesn't have Google Play access and does not support running Android apps. PCs running ChromeOS Flex cannot run Windows virtual machines using Parallels Desktop. Lastly, support for the Linux development environment in ChromeOS Flex depends on your PC and whether Google certified it.

When it makes sense to update your computer with ChromeOS

If you have old PCs and laptops that are too slow to use, consider installing ChromeOS Flex. They are ideal for large enterprises and educational institutions with old computers that can't handle the workload.

For enterprises, Google provides Chrome Enterprise Upgrade to remotely manage all ChromeOS Flex-running PCs. You can remotely wipe them, control their updates, tweak system settings, and more. This is a paid service, and a 30-day free trial is available.

Google claims enterprises can get up to a 295% return on their investment with Chromebooks and save three hours per device per worker over a three-year period. If your company cannot afford to switch to Chromebooks at once due to the size of the investment, ChromeOS Flex is a viable solution as it works on existing hardware.

Google maintains a list of certified models for ChromeOS Flex along with their End of Support year. This is a great way to know how well the OS can perform on your old PC and whether you could encounter problems. If the list says you might run into significant issues with ChromeOS Flex on your computer, it may be best to put off the installation.

Google guarantees audio input/output, video output, network, touchpad, sleep, System UI and graphics, and webcam functionality on certified devices.

Google does not guarantee that installing ChromeOS Flex will make your old PC run as fast as a Chromebook. Your PC's specs and other factors determine ChromeOS Flex's boot speed, power savings, and battery life improvements.

How frequently is ChromeOS Flex updated?

ChromeOS Flex is on the same update cycle as ChromeOS . You'll receive an OS update about every four weeks, while minor security fixes are available once every couple of weeks.

Google rolls out ChromeOS Flex updates in stages, so they might not be instantly available for your PC. Typically, updates take anywhere from a week to two weeks to reach all users. You can manually pull the latest ChromeOS Flex release if you don't want to wait.

Google provides Smart Update Filtering to ensure an update is compatible with the hardware. If the update server detects hardware components in your PC that could have issues with the latest ChromeOS Flex release, the update may not happen as usual. However, the filtering usually only works for critical issues that could prevent your PC from booting or cause graphics or internet connectivity issues.

All the things you need to download ChromeOS Flex

Before you begin the process, have the following on hand to ensure easy and quick installation:

• A PC, Windows laptop, or Mac that you can download ChromeOS Flex on.
• A USB drive to download the ChromeOS Flex installation media. Make sure it has sufficient storage space of at least 8 GB.
• A stable and reliable internet connection is crucial for downloading ChromeOS Flex and any updates or drivers you might need during the installation.
• A spare PC or laptop to download the ChromeOS Flex operating system and create a bootable USB installer.

How to open the Task Manager on Mac and monitor load

Similarly to the Windows equivalent, in the Apple Task Manager you can easily close programs that are frozen or hanging . But if you want more details about a problem, you’ll need to open the Mac Activity Monitor. This lets you kill unused or unresponsive applications, and consult statistics on CPU and memory load, and energy use . But how do you open the Task Manager on a Mac? And what information is shown in the Activity Monitor? We’ve put together a step-by-step guide to help you out.

Force quitting programs using the Mac Task Manager

The Mac Task Manager is a mini-version of the Activity Monitor. To open it, simultaneously press down the [CMD] + [ALT] + [ESC] keys on your keyboard. This will open a window containing a list of all currently opened programs and applications that are running in the background. Select the program or application that has frozen and click on the “Force Quit” button to close it.

The Alt key is also referred to as the Option key. In fact, on some keyboards it is actually labeled “Option”.

Mac Activity Monitor and CPU load

Like the Task Manager, the Mac Activity Monitor also lists all of the processes that are running on the system. You can open it by going into Applications and selecting Utilities , or searching for it directly in Spotlight by clicking on the magnifying glass in the upper-right corner of the menu bar.

The Mac Activity Monitor is split into several sections: CPU, Memory, Energy, Disk, Network, and (in later versions) Cache . The list of processes includes user apps, system apps used by the operating system, and invisible background processes. You can choose which columns to display and filter the processes by going into the “View” menu. As well as the Mac Activity Monitor, you can also install other programs such as  htop  to manage system processes.

The “CPU” pane shows how different processes are affecting CPU performance . Alongside the stats in the “Energy” pane, this information can help you work out what processes are affecting the performance, battery runtime, temperature and fan activity of your Mac. Just below the main window, you will see an additional section containing the following information:

• System : Percentage of CPU capability currently being used by system processes.
• User : Percentage of CPU capability currently being used by apps or processes launched by the user.
• Idle : Percentage of CPU capability not in use.
• CPU Load : Percentage of CPU capability currently being used by all processes (System and User combined).
• Threads : Total number of threads used across all processes.
• Processes : Total number of processes that are currently running.

When you open the Activity Monitor, you might notice that the CPU load for the kernel_task process is rather high, and also that the fan is working harder than usual. One of the roles of kernel_task is to regulate the temperature of the CPU .

The Memory pane of the Mac Activity Monitor tells you how memory is currently being used . The section at the bottom shows the following statistics:

• Memory Pressure : This is a graph that illustrates the availability of memory resources.
• Physical Memory : Total amount of RAM installed.
• Memory Used : Total amount of RAM currently in use.
• App Memory : Total amount of memory currently being used by apps and their processes.
• Wired Memory : Memory that cannot be compressed or paged out to the hard drive and that must therefore remain in RAM.
• Compressed : Amount of RAM that is compressed to make space for other processes.
• Swap Used : Space that the memory management system of the OS is using on your startup drive.
• Cached Files : Memory that was recently used by apps but is now available to other apps.

The “Energy” pane provides information on overall energy use and tells you how much energy is being used by each app. As in the other views, you can click the column headings to sort the processes according to the values measured. The bottom pane shows the following:

• Energy Impact : Total energy used by all apps.
• Graphics Card : Type of graphics card installed.
• Remaining Charge : Percentage of battery charge remaining.
• Time Until Full : Amount of time the Mac must be plugged into the mains before it is fully charged.
• Time on AC : Time elapsed since the Mac was plugged in.
• Time Remaining : Estimated amount of time the Mac can keep running on battery.
• Time on Battery : Time elapsed since the Mac was unplugged.
• Battery (Last 12 hours): Battery charge level over the last 12 hours.

The “Disk” pane shows how much data each process has read from or written to your disk. It also shows “reads in” and “writes out” (IO), that is, the number of times your Mac accesses the disk to read and write data. The information at the bottom of the “Disk” pane shows the total disk activity for all processes combined.

In the “Network” pane you can see how much data your Mac is sending and receiving over the network. This allows you to identify processes that are sending or receiving the largest amounts of data . The information at the bottom of the “Network” pane shows the total network activity for all apps combined.

In macOS High Sierra 10.13.4 or later, the Activity Monitor has an additional pane called “Cache” (if Content Caching is enabled in the “Sharing” pane of System Preferences). This pane shows information such as how much cached content local network devices have uploaded, downloaded or dropped over time.

The information available in the Activity Monitor will depend on what Apple devices and macOS version you are using.
