When an app stops responding, force quit is your fastest option

When a Mac process freezes or stops responding to clicks, you do not have to restart your computer. You can force the app to close using the keyboard shortcut Command + Option + Esc, which opens the Force Quit window. Select the frozen app from the list and click "Force Quit" — the app will close when ready, and you can reopen it fresh.

This is different from a normal quit. A normal quit (Command + Q) asks the app to close politely and save its work. Force quit bypasses that request and shuts the app down right away. You may lose unsaved work in that app, but the rest of your Mac stays unaffected.

Key Takeaways

  • Press Command + Option + Esc to open the Force Quit window, then select the frozen app and click "Force Quit".
  • Force quit closes only the stuck app — it does not restart your Mac or affect other open programs.
  • You may lose unsaved changes in the frozen app, but your other work remains safe.
  • If an app freezes repeatedly, restart your Mac before reopening it, as a frozen app sometimes leaves processes running in the background.
  • Activity Monitor is an alternative method if the Force Quit window does not appear or does not respond.

Using the keyboard shortcut (fastest method)

The quickest way to force quit is the keyboard shortcut. Hold down Command + Option + Esc at the same time. You will see a window titled "Force Quit Applications" appear within a second or two.

Look at the list of open apps. The frozen app will usually say "not responding" next to its name in red text. Click on that app name to select it, then click the "Force Quit" button in the bottom right of the window. The app closes when ready.

After the app closes, you can close the Force Quit window by clicking the red button in the top left corner, or just click elsewhere on your desktop. Your Mac is ready to use again.

Using Activity Monitor if the shortcut does not work

Occasionally the Force Quit window itself becomes unresponsive or does not appear. In that case, use Activity Monitor, which is a more detailed tool for managing running processes. Open Spotlight search by pressing Command + Space, type "Activity Monitor", and press Enter.

Activity Monitor shows every app and background process running on your Mac. Look for the app that is frozen — it will often have "(Not Responding)" next to its name. Click on it once to select it, then click the "X" button in the top left of the Activity Monitor window labeled "Force Quit".

A confirmation dialog will appear asking if you want to force the app to quit. Click "Force Quit" again to confirm. The app closes, and you can close Activity Monitor.

What happens to unsaved work

When you force quit an app, any changes you made but did not save are lost. If you were working on a document, email, or any other file and had not saved it, that work will not be recovered. This is the trade-off for stopping a frozen app when ready.

Some apps (like Google Chrome and Microsoft Word) have recovery features that can reopen your work the next time you launch them, but this is not may provide. To avoid losing work, save your files regularly while you are working, especially in apps that have frozen before.

Restarting your Mac after a force quit

If an app freezes once, force quitting and reopening it usually solves the problem. However, if the same app freezes repeatedly, restart your Mac before opening it again. A frozen app sometimes leaves background processes running even after you force quit it, and a restart clears those out completely.

To restart, click the Apple menu in the top left, select "Restart", and click "Restart" again in the confirmation dialog. Your Mac will close all apps and restart. This takes a few minutes but often fixes apps that keep freezing.

Preventing apps from freezing in the future

Apps freeze most often when they run out of memory or when a background process gets stuck. Keeping your Mac updated helps — app updates often fix bugs that cause freezing. You can check for updates by clicking the Apple menu, selecting "System Settings", clicking "General", and then "Software Update".

You can also reduce freezing by closing apps you are not using, especially if you have many browser tabs open. Each open app and tab uses memory, and when your Mac runs low on memory, apps slow down and freeze. If you notice an app always freezes when you have many other things open, that is a sign memory is the problem.

Frequently Asked Questions

Will force quitting damage my Mac?

No. Force quitting closes only the frozen app. It does not affect your Mac's operating system, other open apps, or your files. The only loss is unsaved work in the app you force quit.

What if force quit does not work?

If the Force Quit window does not appear or does not respond, restart your Mac. Hold the power button for ten seconds until your Mac shuts down, then press it again to turn it back on. A restart forces all frozen processes to close.

Can I force quit multiple apps at once?

The Force Quit window lets you select and close one app at a time. If multiple apps are frozen, force quit them one by one. Activity Monitor lets you select multiple apps by holding Command and clicking each one, then force quit them together.

Why does my app keep freezing?

Repeated freezing usually means the app has a bug, your Mac is low on memory, or the app is outdated. Update the app through the App Store or the app's website, close other programs to free up memory, or uninstall and reinstall the app if freezing continues.

Do I lose everything when I force quit?

You lose only unsaved work in the app you force quit. All your other open apps, files, and the rest of your Mac remain untouched. Restart your Mac afterward if the app was frozen for a long time, as background processes may still be running.
