Force closing an app on your Mac when it stops responding
When a Mac app freezes or stops responding, you do not have to restart your entire computer. You can force close just that one app in about 10 seconds using the Force Quit window. This is the same as force closing on any other device — the app shuts down immediately, and you can reopen it fresh.
The app will not save any unsaved work when you force close it, so this is a last resort when an app is truly stuck. But it will not harm your Mac or other open apps, and it is the fastest way to get an unresponsive program off your screen.
Key Takeaways
- Press Command + Option + Esc to open the Force Quit window, select the frozen app, and click Force Quit.
- Any unsaved work in that app will be lost when you force close it, so this is only for apps that have completely stopped responding.
- Force closing one app does not affect other open programs or your Mac itself.
- If an app freezes repeatedly, try updating it or reinstalling it after you force close it.
The keyboard shortcut method (fastest)
The quickest way to force close an app is with a keyboard shortcut. Press Command + Option + Esc all at the same time. Your Mac will open a small window titled "Force Quit Applications."
Look for the app that is frozen or not responding — it will usually have the word "not responding" next to its name in the list. Click on it once to select it, then click the Force Quit button in the bottom right of the window. The app will close immediately.
After the app closes, you can click the red close button on the Force Quit window or press Escape to close that window too. Then reopen the app normally if you need it.
Using the Apple menu if the keyboard shortcut does not work
If the keyboard shortcut does not work — sometimes because the app has locked up your keyboard input — you can reach Force Quit through the menu instead. Click the Apple menu (the apple symbol) in the top left corner of your screen.
Scroll down and click Force Quit. This opens the same Force Quit window as the keyboard shortcut. Find the frozen app in the list, click it, and click Force Quit again. The process is identical; it just takes a few more clicks to get there.
What happens to your work when you force close
When you force close an app, any changes you made but did not save will be lost. If you were writing an email, editing a document, or working on anything else, that unsaved work disappears. This is why force closing should only be your move when the app is completely unresponsive and you cannot save or close it normally.
Some apps like Google Docs or iCloud-synced notes may recover recent work because they save to the cloud automatically, but do not count on this. If you have unsaved work you care about, try waiting a few seconds first — sometimes an app is just slow, not actually frozen. If it truly will not respond to any clicks or keyboard input after 30 seconds, then force close is the right choice.
Preventing the same app from freezing again
If an app freezes regularly, the problem is usually an outdated version or a conflict with another program. The first step is to update the app. Open the App Store, click Updates in the top menu, and look for the app in the list. If an update is available, click Update next to it.
If updating does not solve the problem, try uninstalling and reinstalling the app. Drag the app from your Applications folder to the Trash, empty the Trash, then download the app fresh from the App Store or the developer's website. This clears out any corrupted files that might be causing the freeze.
If the app still freezes after reinstalling, the problem may be with your Mac itself — too many apps running at once, not enough storage space, or a need to restart. Try closing other apps before opening the one that was freezing, or restart your Mac and try again.
The difference between force closing and restarting
Force closing shuts down only the frozen app. Everything else on your Mac keeps running — your other open apps, your documents, your browser tabs. You lose only the unsaved work in that one app.
Restarting your entire Mac is a bigger step that closes everything and starts fresh. You would only restart if force closing does not work, if multiple apps are frozen, or if your Mac itself is running slowly. For a single frozen app, force close is faster and less disruptive.
Frequently Asked Questions
Will force closing damage my Mac or lose files I already saved?
No. Force closing shuts down only that one app and does not affect your Mac hardware or files you have already saved to disk. You will only lose unsaved work that was open in that specific app at the moment you force closed it.
What if the Force Quit window itself will not open?
If Command + Option + Esc does not work, try the Apple menu route instead. If neither works and your entire Mac is frozen, hold down the power button for 10 seconds to force shut down your Mac, then turn it back on. This is a last resort and should only be used when nothing else responds.
Can I force close an app without losing my work?
Not with force close — that command closes the app immediately without saving. If the app is responding at all, try using File > Save first, then close the app normally. Force close is only for apps that have completely stopped responding to any input.
Do I need to restart my Mac after force closing an app?
No. You can reopen the app right away or keep working in other apps. Force closing one app does not require a restart unless the app was so broken that it affected your entire system, which is rare.
