Understanding the root of some problems can be difficult; fortunately, there are some troubleshooting tools to diagnose what’s wrong with your Mac.

Dec 20, 2016  Activity Monitor. To launch Activity Monitor, select Applications, Utilities and Activity Monitor. You will be presented with a large window showing CPU usage with a scrolling display of the apps using percentages of CPU clock time in descending order. The app or process listed at the top is currently using the most CPU.

One of such tools is the Activity Monitor, and in this article we’ll tell you how to use it, what alternatives are out there, and how to maintain your Mac to avoid different problems. So let’s start!

Activity Monitor — The Task Manager for Mac

If you’re familiar with the Windows Task Manager, then you may wonder whether there is a twin for Mac. Don’t worry, a Task Manager exists on Macs but it has another name — Activity Monitor. Just keep in mind that Activity Monitor is the Mac Task Manager equivalent and functions in a very similar way as it does in Windows.

Activity Monitor shows the processes that are running on your computer, so you can see how they affect your Mac’s performance. This important tool will help you manage your Mac’s activity, so you should know how to use it at its full potential.

How to open Task Manager on Mac

Activity Monitor is located in the /Applications/Utilities/ folder and there are a few ways to launch it. The simplest one is to use Spotlight for a quick search.

Here’s how to access Task Manager on Mac using the Spotlight:

Good news, you can avoid the long ways of opening a Task Manager by pinning it to the Dock. Once you do it, you’ll be able to access the Activity Monitor by simply clicking on its icon.

Follow these steps and you won’t keep asking yourself how to start Task Manager on Mac every time you need to check some processes:

  1. Open the Activity Monitor using one of the ways described above.
  2. Right-click on the Activity Monitor icon in the Dock.
  3. In the menu, choose Options and then click Keep in Dock.

That’s it! The Activity Monitor will be available from the Dock of your Mac, so you can view it easily.

How to use the Activity Monitor

The Activity Monitor is a simple but very important tool. Find out what you can do with its help.

Monitor the system parameters

Once you open the Activity Monitor on your Mac, you’ll get access to the five tabs: CPU, Memory, Energy, Disk, and Network. By analyzing the data, you can identify what processes affect your Mac performance.

  • The CPU pane shows how processes are affecting the processor activity.
  • The Memory pane shows how the RAM is used by apps on your Mac.
  • Tap on the Energy pane and you’ll see the overall energy use and the energy used by each app.
  • The Disk pane shows the amount of data that each process has read from your disk and has written to it.
  • Use the Network pane to identify which processes send and receive the most data.

View additional info about an app or process

The Mac Task Manager also allows you to check the additional information about every application or process on your Mac. Here’s how to view it:

  1. Click on the application or process you’re interested in.
  2. Click on the i button in the top left corner of the Activity Monitor window.
  3. You’ll see a pop-up window showing additional information about an app or process.

As you see, the Activity Monitor is a real gem. It helps you gain insight into many useful things. Therefore, it will be much easier to diagnose any problem your Mac has.

How to Force Quit applications from a Task Manager in Mac

If some application or program freezes and you can’t quit it normally, you can use the Activity Monitor to shut it down. To force quit an app from a Mac Task Manager, do the following:

  1. Open the Activity Monitor on your Mac and click on the application you want to force quit.
  2. Then click on the X button in the top left corner of the Activity Monitor window.
  3. You will see a pop-up window asking if you want to quit this process.
  4. Click Quit to close the unresponsive app.
  5. If the app is still open, choose Force Quit to immediately end the process.

What’s a Control+Alt+Delete equivalent on Mac?

All Windows users know this magic combination: Control+Alt+Delete. The first thing they do when an app or program hangs is using this keyboard shortcut. Fear not: there’s the similar shortcut for Macs.

In addition to the Activity Monitor, Macs have a Force Quit Applications Manager that allows to close the frozen apps and programs. To open it, hold down the Command+Option+Escape keys.

If you just need to force quit an application and don’t care how much CPU or Energy it is using, then you should launch a Force Quit Applications Manager to perform the task. It gives an immediate access to all apps, so you can quickly solve the problem of an unresponsive program.

When your Mac slows down or starts behaving erratically, chances are it's because an application that's running, perhaps in the background, is misbehaving. And if it's not an application that's causing the problem, it will almost certainly be a process associated with macOS or an ancillary service.

Solving this problem is usually as simple as killing the process, but in order to do that you need to identify which one.Here's a comprehensive guide on how to view and kill processes on your Mac.

Best task killers for Mac

Try the best tools that help you find and kill processes hampering your Mac's performance.

How to show which processes consume a lot of memory

The easiest way to view all active processes running on your Mac is to launch Activity Monitor from your Applications folder. In the default CPU tab, you can see how much processing power every process takes, ranked by the most consuming. And if you switch to the Memory tab, you will see the same list ranked by the amount of used up RAM.

For more immediate and elaborate information on how your computer resources are consumed, use iStat Menus, which handily lives in your menu bar and, in its MEM table, shows you applications and processes that are consuming more than their fair share of RAM in real time.

How to kill process using Activity Monitor

  1. Launch Activity Monitor.
    The easiest way to launch Activity Monitor is to press Command and spacebar to call up Spotlight, then start typing Activity Monitor. When it appears in Spotlight, hit Return to launch it. Alternatively, go to Utilities in the Applications folder and double-click on its icon. Or open Activity Monitor in one click through iStat Menus app.
  2. View and filter tasks.
    You'll notice there are five tabs across the top of the Activity Monitor window: CPU, Energy, Memory, Disk, and Network. Clicking on any of those tabs organizes processes according to the percentage of the resource they are using. So, clicking on CPU lists tasks in the order of how much CPU capacity they're using. By default, processes are ordered starting with the one that's consuming the most of the resource at the top, so you can quickly see where problems are occurring or likely to occur. To flip the order, so that processes consuming the least of the resource are at the top, click the arrow next to Memory or CPU above the list of processes.
  3. Kill problematic processes.
    When you identify a process that's causing a problem, either because it's hogging lots of CPU cycles or memory, or because it's highlighted in the Activity Monitor as having crashed, you need to kill it. To do that, click on the process first and then on the X in the Activity Monitor toolbar. The process will quit and free up the resources it was taking up. If it's a critical process, it will restart. If it's an application, it will remain shut down.

Activity Monitor alternatives

How to shut down processes using Terminal

  1. Launch Terminal. Press Command and spacebar to pull up Spotlight then start typing Terminal. When the Terminal app appears in Spotlight, tap Return to launch it. Alternatively, navigate to the Utilities folder in Applications and double-click Terminal.
  2. View processes. When Terminal has launched, type 'top' into the Terminal window. You'll see a list of currently running processes. At the top of the list is an overview of the processes that are running and the resources they're consuming.
  3. Kill an unwanted process. When you identify a process that's causing a problem or consuming too many resources, take note of the number in the PID column next to the name of the process. To kill the process, type 'kill -9' followed by the PID number. Press Enter. The problem process will now quit.

How to prevent problematic processes

You can pretty much avoid issues altogether by being a little bit proactive in hunting down the common culprits. Here, iStat Menus will help you identify which applications or processes are consuming finite resources, such as CPU and RAM.

Then, you can use CleanMyMac maintenance routines that, when run regularly, will keep you Mac running smoothly. Here's how to do that:

  1. Launch Setapp and search for CleanMyMac.
  2. Find the maintenance scripts. Under the Speed section in the left sidebar, click on Maintenance. You will see a list of tasks that CleanMyMac would suggest you to perform to optimize your Mac. You should try to run them all, but the one especially important for us is under Run Maintenance Scripts.
  3. Run the maintenance scripts. Click on the checkbox next to Run Maintenance Scripts and then click Run. Alternatively, choose another specific maintenance script such as Speed Up Mail or Reindex Spotlight and click Run. When it's finished, click Select Tasks to return to the list of maintenance tasks.

Run other tasks, as necessary. If you're having problems with Mail, repeat step 3, but this time click the checkbox next to Speed Up Mail. Likewise, if Spotlight is running slowly, run the Reindex Spotlight task.

How to kill a background process

To kill a background process, use Activity Monitor. While the steps are the same as described in the 'How to kill a running process using Activity Monitor' section above, the key difference is that background processes often have obscure names that don't clearly describe what they do.

Be careful when killing a background process and, if not sure, leave it alone or search online for its exact role in your system. Otherwise, you might risk causes problems for your macOS. Generally, background processes don't tend to consume significant RAM or CPU cycles, so if you spot one that does, it has probably got into trouble. Kill it using the X in the Activity Monitor toolbar.

How to easily remove startup items

One common cause of Macs running slowly or having problems is items that launch automatically at startup. These could be helper apps for something like iTunes or just complete apps in their own right. They are also frequently apps you once used but no longer need.

To review the apps and helpers that startup when you log in

  1. Launch System Preferences from the Apple menu and click on the Users & Groups pane.
  2. Click the padlock and type in your password.
  3. Then select your username in the left panel and click the Login Items tab.
  4. Look through all the login items that correspond to apps you no longer use and then click the minus button. The app will no longer start up automatically when you log in.

How to Force Quit an application that's not responding

If you see the dreaded spinning beachball, or an app just won't do anything, you should force quit it.

There are several ways to force quit an unresponsive application:

  1. Press Command-Alt-Esc and click on the application in the window that opens. Press Force Quit
  2. Control-click or right-click on the application's icon in the Dock and choose Force Quit
  3. Launch Activity Monitor, locate the application and press the 'x' in the toolbar
  4. Locate the process in Activity monitor, look for the entry in the PID column and launch Terminal. Type 'kill -9' followed by the PID number. Press Enter

Fix crashing apps with Spindump

While Force Quit will fix the problem, it’s a temporary solution. If you’re determined to identify the source of crashing apps and prevent them from happening, use Spindump on Mac. It’s a hang reporting tool that alerts you about the crash and helps share the details with the app developer.

Whenever the app crashes, it will trigger Spindump and send the information to Apple or the app developer. Not only does it help you understand what just happened, but it also helps the developer track the conditions of app misbehavior — and fix it accordingly. A win-win.

How to create a Spindump file on Mac

Activity Monitor Mac App Nap
  1. Launch Activity Monitor via Applications > Utilities
  2. Pick the app for which you want to create a Spindump file, then click on the Settings icon
  3. Select Spindump or Run Spindump
  4. Wait a few seconds for the file to generate
  5. Click Save.


Reset a problematic app

There's one more thing you can try if an app keeps running slowly or crashing – reset it. Thanks to CleanMyMac, resetting an app is easy. Here's what you need to do:

  1. Locate the uninstaller. In the left hand sidebar of CleanMyMac, click on Uninstaller under Applications.
  2. Find the app that's causing a problem. Scroll through the list of apps until you find the one that's been crashing or running slowly. Click on it to highlight.
  3. Reset the app. With the app highlighted, you'll see all the files associated with it in the right-hand window. Click Application Reset at the top of the window and all the files, except the main application file, will be selected.
  4. Click Uninstall. All the selected files will be trashed, effectively resetting the application to its default state. When you launch it the next time, it will behave as if it has just been installed — so you'll need to recreate any custom settings or preferences.

If resetting the app doesn't work, the final resort should be to uninstall the app completely and reinstall it. To do that, click Complete Uninstallation in the same menu instead of Application Reset.

As you can see there are lots of different ways and apps that help you view and kill processes in macOS. iStat Menus is a great way to passively monitor which processes are causing problems, so you can launch Activity Monitor and quit them. And running CleanMyMac's maintenance scripts regularly prevents problems occurring in the first place. Best of all, all these apps are available to try for free on Setapp, along with over 120 high-quality macOS apps. So check your Mac for problematic processes now and see what you find.
