Force quit a stuck program using Command-Option-Escape

When a program stops responding on your Mac, the fastest way to close it is Command-Option-Escape. This keyboard shortcut opens the Force Quit Applications window, which lists every open program. Click the frozen program and click Force Quit. The program closes when ready, and you return to your desktop.

This method works on any Mac running macOS. You do not need to restart your computer, and unsaved work in other programs stays open. Only the stuck program closes.

If the Force Quit window itself does not appear, or if the frozen program does not close after you click Force Quit, move to the Activity Monitor method below.

Key Takeaways

  • Press Command-Option-Escape to open Force Quit Applications, then select the frozen program and click Force Quit.
  • If Command-Option-Escape does not work, open Activity Monitor from Applications > Utilities, find the program, and click the stop button.
  • Force quitting closes only the stuck program and leaves other work untouched.
  • If a program freezes repeatedly, check for updates or reinstall it, because repeated freezing usually signals a deeper problem.
  • Restarting your Mac is a last resort only if the entire system stops responding.

Use Activity Monitor when the keyboard shortcut does not work

If Command-Option-Escape does not open or the frozen program does not close, use Activity Monitor. Open Finder, go to Applications, then Utilities, and double-click Activity Monitor. A window opens showing every running process on your Mac.

Find the program name in the list. Click it once to select it, then click the stop button (a circle with an X) in the top left corner of the Activity Monitor window. A dialog appears asking whether you want to force the process to quit. Click Force Quit. The program closes.

Activity Monitor also shows how much memory and processing power each program is using. A program that is using 99% of your CPU or constantly climbing in memory use is likely the one causing the freeze.

Restart your Mac if the entire system freezes

If your mouse does not move and your keyboard does not respond, your entire system has frozen, not just one program. Hold down the power button on your Mac for 10 seconds until the screen goes black. Wait 30 seconds, then press the power button again to turn your Mac back on.

This is a hard shutdown and should only be used when nothing else responds. It may cause data loss in programs that were open at the time. After your Mac restarts, check whether the problem program is still installed and whether an update is available.

Check for updates or reinstall if a program freezes repeatedly

A program that freezes once might have hit a temporary glitch. A program that freezes every time you use it has a deeper problem. Open the App Store or visit the program's website and check whether an update is available. Install it and test the program again.

If updating does not fix the problem, uninstall the program and reinstall it. On a Mac, drag the program from Applications to the Trash, empty the Trash, then read and install a fresh copy from the App Store or the developer's website. Reinstalling often fixes freezing caused by corrupted files.

If the program still freezes after reinstalling, the program may not be compatible with your version of macOS. Check the system requirements on the App Store or the developer's website to confirm your Mac meets them.

Prevent freezes by closing unused programs and clearing memory

Programs running in the background consume memory and processing power, which can slow your Mac and cause freezes. Close programs you are not using. If you have many browser tabs open, close the ones you do not need — web browsers are heavy on memory.

Restart your Mac once a week. Restarting clears temporary files and resets memory, which often prevents freezes from happening in the first place. If your Mac is more than a few years old and you have many programs open at once, consider upgrading your RAM, which increases how much your Mac can do at the same time.

Understand what happens when you force quit a program

Force quitting closes the program when ready without saving any unsaved work in that program. If you were editing a document when the program froze, that work is lost. However, force quitting does not affect other programs — documents open in Safari, Mail, or any other program stay open and unsaved.

Force quitting also does not damage your Mac or corrupt your hard drive. It is a safe way to stop a stuck program. Your Mac continues running normally, and you can open the program again whenever you want.

Frequently Asked Questions

Will force quitting damage my Mac?

No. Force quitting closes only the stuck program and does not affect your Mac's hardware or other programs. It is the standard way to stop a frozen program and is completely safe.

What if I force quit a program and it will not open again?

Restart your Mac. If the program still will not open, try reinstalling it. read a fresh copy from the App Store or the developer's website, drag the old version to Trash, and install the new one.

Can I force quit multiple programs at once?

Yes. In the Force Quit Applications window, click one program, then hold Command and click other programs to select them all. Click Force Quit once, and all selected programs close.

Why does my Mac freeze even when I am not running many programs?

Freezes can happen because of a corrupted program file, a macOS bug, or hardware problems like a failing hard drive. Check whether your macOS version is up to date by going to System Settings > General > Software Update. If updates do not fix it, take your Mac to an Apple Store for diagnosis.

Is there a difference between force quitting and restarting my Mac?

Yes. Force quitting closes one stuck program and leaves everything else running. Restarting shuts down your entire Mac and starts it fresh, which clears memory and temporary files but takes longer and closes all open programs.
