The fastest way to force close an app on Mac
Press 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. The window stays open until you close it, so you can force quit multiple apps in one session if needed.
If the keyboard shortcut does not work — for example, if your Mac is severely frozen — you can also reach Force Quit through the Apple menu. Click the Apple logo in the top-left corner, then select Force Quit.
Key Takeaways
- Command + Option + Esc opens the Force Quit window on any Mac, letting you shut down frozen or unresponsive apps instantly.
- The Force Quit button closes the selected app without saving, so unsaved work in that app will be lost.
- If the keyboard shortcut fails, use the Apple menu instead: click the Apple logo, then Force Quit.
- Activity Monitor offers more detail about what an app is doing before you force close it, useful if you want to understand why it stopped responding.
- Force closing an app does not affect other open programs or your Mac's overall performance.
What happens when you force close an app
Force closing shuts down the app immediately without letting it save your work. Any unsaved documents, text, or changes in that app will be lost. If you have been working on something important, save it in another app or another window before you force quit.
The rest of your Mac keeps running normally. Other open apps are not affected, and your Mac does not need to restart. Once the app closes, you can open it again right away if you want to.
Using Activity Monitor for more control
Activity Monitor is a built-in Mac tool that shows you what every app is doing — how much memory it is using, how much processor power, and whether it is actually frozen or just slow. 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, then click the X button in the top-left corner of the Activity Monitor window. A dialog will appear asking you to confirm; click Force Quit. This method takes a few more steps than the keyboard shortcut, but it lets you see exactly what the app was doing before it stopped responding.
Activity Monitor is especially useful if multiple apps have similar names or if you want to check whether an app is actually frozen or just using a lot of processor power and will respond if you wait a moment longer.
When an app keeps freezing
If an app freezes regularly, force closing it is a temporary fix, not a solution. The real problem is usually that the app needs an update, your Mac is running low on storage space, or the app has a bug that the developer knows about.
Check the App Store or the app's website to see if a newer version is available. If an update exists, install it and try using the app again. If the app still freezes after updating, try restarting your Mac — many apps behave better after a restart because it clears out temporary files and resets memory.
If restarting and updating do not help, the app may not be compatible with your version of macOS, or it may have a known issue. Search online for the app name plus "freezes" or "not responding" to see if other people have reported the same problem and found a workaround.
Force closing vs. quitting normally
Quitting an app normally — by pressing Command + Q or clicking the app name in the menu bar and selecting Quit — gives the app a chance to save your work and close cleanly. Force closing skips all of that and shuts the app down immediately.
Use normal quit when the app is responding and you have finished using it. Use force quit only when the app is frozen, not responding to clicks, or stuck on a loading screen. Forcing quit an app that is working fine can occasionally cause problems, though it is generally safe.
If your entire Mac is frozen
If your whole Mac is frozen and the keyboard shortcut does not work, try holding down the power button for 10 seconds until the Mac shuts down completely. Wait a few seconds, then press the power button again to turn it back on. This is a last resort and should only be used when nothing else works.
After a forced shutdown, your Mac will restart normally. Some apps may show a recovery dialog the next time you open them, asking whether you want to recover unsaved work. Click Recover if you want to try to get back what you were working on.
Frequently Asked Questions
Will force closing an app damage my Mac?
No. Force closing an app only shuts down that one program. Your Mac's operating system and other apps are not affected. You can force close apps as often as you need to without harming your computer.
Can I force close the Finder or System apps?
The Finder and core system apps like Spotlight usually cannot be force quit because macOS protects them. If you try to force quit one of these apps, the button will be grayed out or the action will not work. If the Finder is frozen, restarting your Mac is usually the best option.
What if an app does not appear in the Force Quit window?
If an app is not listed, it may have already closed on its own, or it may be running in the background without a visible window. Open Activity Monitor to see all running processes, including background apps. Search for the app name in the list and force quit it from there.
Does force closing delete the app from my Mac?
No. Force closing only stops the app from running. The app itself remains installed on your Mac and you can open it again whenever you want. To remove an app permanently, you would need to uninstall it separately.
Why does my app keep freezing after I force close it?
Repeated freezing usually means the app needs an update, your Mac is low on storage, or there is a compatibility issue. Check the App Store for updates, restart your Mac, and make sure you have at least a few gigabytes of free space. If the problem continues, the app may not work well with your version of macOS.
