How To Open And Use Task Manager On A Mac

If you’re looking for the equivalent of Windows Task Manager on Mac, here we show you how to open and use the Activity Monitor on a Mac including on both Intel and Apple Silicon Macs.

On Windows, pressing Ctrl-Alt-Delete brings up the Task Manager so that you can Force Quit applications and programs that have either crashed or are running slowly.

There are various ways to Force Quit on a Mac the easiest being using the mini equivalent of Task Manager by pressing the Command + Option + Esc keys.

However, the version of Task Manager accessible by the Command + Option + Esc keyboard shortcut doesn’t always shut-down the program that’s locked-up and it doesn’t give you any further information on what’s causing the problem.

Like Windows Task Manager, Activity Monitor also allows you to close files and applications that may be behaving unexpectedly or not functioning properly but also provides far more detailed information on memory usage, CPU usage and other processes running on your Mac.
