The fastest way to force close an app on Mac

Hold Command + Option + Esc to open the Force Quit Applications window. Click the app you want to close, then click the Force Quit button. The app will shut down immediately, even if it is frozen or not responding.

This keyboard shortcut works on any Mac running macOS and is faster than using the menu bar. You do not need to save your work first — the app will close without warning, so you will lose any unsaved changes in that program.

If the Force Quit window does not appear, your Mac may be completely unresponsive. In that case, hold the power button for ten seconds to force your Mac to shut down, then turn it back on.

Key Takeaways

  • Command + Option + Esc opens the Force Quit window, where you select the frozen app and click Force Quit.
  • Force closing an app closes it immediately without saving, so you will lose any work you have not saved to disk.
  • Activity Monitor is an alternative method that shows you how much memory and CPU each app is using before you close it.
  • If your entire Mac is frozen and Force Quit does not work, hold the power button for ten seconds to shut down.
  • Most apps that freeze will respond again after a few seconds, so wait briefly before force closing if the app is just slow.

Using Activity Monitor to close apps

Open Activity Monitor by pressing Command + Space, typing "Activity Monitor", and pressing Enter. Find the app you want to close in the list, click it once to select it, then click the X button in the top left corner of the window.

Activity Monitor shows you how much memory and CPU each running app is using. This is useful if you want to see which app is slowing down your Mac before you close it. You can also sort by CPU or Memory to see the heaviest apps at the top.

When you click the X button, a dialog will ask whether you want to quit or force quit. Click Force Quit if the app is not responding. If the app closes normally, your unsaved work may still be recoverable through the app's recovery features.

When an app is frozen but your Mac is not

If only one app is frozen and the rest of your Mac is working normally, use Command + Option + Esc first. It is the fastest method and requires no navigation through menus or windows.

Wait a few seconds before force closing. Some apps pause briefly when they are loading a large file or performing a heavy task. If you force close too quickly, you may lose work unnecessarily. If the app is still frozen after ten seconds, it is safe to force close.

After you force close an app, try opening it again. If it crashes repeatedly, restart your Mac. Restarting clears temporary files and memory that may be causing the problem.

When your entire Mac is frozen

If your Mac does not respond to any keyboard or mouse input, hold the power button on your Mac for ten seconds. Your Mac will shut down completely. Wait a few seconds, then press the power button again to turn it back on.

Do not hold the power button for longer than ten seconds — most Macs will shut down after ten seconds, and holding it longer serves no purpose. If your Mac does not shut down after ten seconds, it may have a hardware problem.

After your Mac restarts, it may show a recovery screen or ask you to log in again. This is normal. If your Mac freezes again shortly after restarting, the problem may be with a specific app or a hardware issue that needs diagnosis.

Preventing apps from freezing

Keep your Mac and your apps updated. Go to System Settings, click General, then click Software Update to check for macOS updates. Open each app's menu and look for an Update option to check for app updates.

Restart your Mac regularly — at least once a week. Restarting clears memory and temporary files that build up over time. A Mac that has been running for weeks without restarting is more likely to have slow or frozen apps.

If one app freezes repeatedly, uninstall it and reinstall the latest version. Open Finder, go to Applications, right-click the app, and click Move to Bin. Then download the latest version from the app's website or the Mac App Store.

Frequently Asked Questions

Will force closing an app delete my files?

Force closing will not delete your files on disk. You will lose any work you have not saved in that app, but your documents and other files remain on your Mac. If the app has a recovery feature, it may restore your unsaved work the next time you open it.

Can I force close the Finder or System apps?

You can force close Finder, but it will reopen immediately. System apps like Spotlight and Siri cannot be force closed. If Finder is frozen, force closing and restarting it often fixes the problem.

What is the difference between quit and force quit?

Quit closes an app normally and gives it time to save your work. Force Quit closes it immediately without saving. Use Force Quit only when an app is frozen and not responding to normal quit commands.

Why does my Mac freeze when I open a specific app?

The app may be outdated, corrupted, or incompatible with your version of macOS. Try updating the app first. If it still freezes, uninstall it and reinstall the latest version. If the problem continues, the app may not be compatible with your Mac.

Is it safe to force close apps regularly?

Force closing occasionally is safe, but if you find yourself force closing the same app repeatedly, something is wrong. Update the app, restart your Mac, or uninstall and reinstall it. Regular force closing suggests the app has a problem that needs fixing.
