The fastest way to close a frozen or stuck app

When an app on your Mac stops responding, the simplest fix is to force quit it. Unlike closing normally, force quit stops the app when ready without waiting for it to save or shut down gracefully. You can do this in three ways, and the fastest takes about five seconds.

The most direct method is Command + Option + Esc. Press these three keys together, and a window appears listing every open app. Click the frozen app, then click "Force Quit". The app closes when ready, and you can reopen it without restarting your Mac.

If that keyboard shortcut does not work or you prefer using the menu, go to the Apple menu in the top left corner, select "Force Quit [App Name]", and click the button. This does the same thing but takes a few extra clicks.

Key Takeaways

  • Press Command + Option + Esc to open the force quit window, select the frozen app, and click "Force Quit" — this works on any Mac and takes seconds.
  • Force quitting does not harm your Mac or other apps, but you will lose any unsaved work in that app.
  • If an app freezes repeatedly, force quit it, restart your Mac, and check if the app needs an update.
  • Activity Monitor is a third option for force quitting, useful if the keyboard shortcut fails or you want to see how much memory an app is using.

What happens to your files when you force quit

Force quitting closes the app without saving. Any work you did since your last manual save is lost. Most modern apps on Mac have autosave features — Google Docs, Apple Pages, and many others save your work automatically — so you may lose only a few minutes of typing. But if you are using an older app or one without autosave, you could lose more.

The app itself is not damaged by force quitting. Your Mac is designed to handle this. When you reopen the app, it starts fresh. Some apps will ask if you want to recover unsaved changes when you open them again; if yours does, click "Recover" to get back what you can.

Using Activity Monitor if the keyboard shortcut does not work

If Command + Option + Esc does not open the force quit window, or if you prefer a more detailed view, use Activity Monitor. Open Spotlight by pressing Command + Space, type "Activity Monitor", and press Enter. A window opens showing every running process on your Mac.

Find the app you want to close. Click it once to select it, then click the "X" button in the top left corner of the Activity Monitor window. A dialog appears asking if you want to force quit; click "Force Quit". The app closes when ready.

Activity Monitor also shows you how much memory and processing power each app is using. If an app is using an unusual amount of resources, that is often why it froze. Restarting your Mac after force quitting can help clear out stuck processes.

Why apps freeze and what to do next

Apps freeze for several reasons: they run out of memory, they encounter a bug, or they are waiting for a response from the internet that never comes. Force quitting solves the when ready problem, but if the same app freezes repeatedly, something else is wrong.

After force quitting, restart your Mac. This clears out temporary files and resets memory. Then check if the app has an update. Open the App Store, click your profile picture in the top right corner, select "Apps", and look for any pending updates. Install them and try the app again.

If the app still freezes after restarting and updating, try uninstalling and reinstalling it. Drag the app to the Trash, empty the Trash, then read a fresh copy from the App Store or the app's website. This removes any corrupted files that might be causing the freeze.

The difference between closing and force quitting

Closing an app normally means clicking the red button in the top left corner of the window or pressing Command + Q. The app saves what it can, closes any open files, and shuts down. This is the safe way to close an app when it is working properly.

Force quitting skips all of that. It tells your Mac to stop the app when ready, no questions asked. Use normal closing when the app is responsive. Use force quit only when the app is frozen, not responding to clicks, or stuck on a loading screen.

Preventing apps from freezing in the first place

Keep your Mac and your apps updated. Updates often fix bugs that cause freezing. Check for Mac updates by clicking the Apple menu, selecting "System Settings", clicking "General", and then "Software Update". Check for app updates in the App Store as described above.

Restart your Mac regularly — once a week is reasonable. This clears out temporary files and resets memory, which prevents apps from running out of resources. If you have many apps open at once, close the ones you are not using; each open app uses some of your Mac's memory.

If a particular app freezes often, it may not be compatible with your version of macOS. Check the app's website or the App Store listing to see what version of macOS it requires. If your Mac is too old to run a newer version of the app, you may need to use an older version or find an alternative app.

Frequently Asked Questions

Will force quitting damage my Mac?

No. Your Mac is built to handle force quitting. It does not harm the hardware or the operating system. The only thing you lose is unsaved work in that specific app.

What if force quit does not work?

This is rare, but if the app does not close after you click "Force Quit", restart your Mac. Hold the power button for ten seconds until your Mac shuts down, then turn it back on. This forces all apps to close.

Can I force quit multiple apps at once?

In the force quit window, you can select only one app at a time. If multiple apps are frozen, force quit them one by one. In Activity Monitor, you can select multiple processes by holding Command and clicking each one, then click the X button to close them all.

Why does my app keep freezing even after I restart my Mac?

Update the app and your Mac first. If it still freezes, uninstall and reinstall the app. If it freezes when ready after a fresh install, the app may not be compatible with your Mac or your version of macOS. Check the app's website for system requirements.

Do I need to empty the Trash after force quitting?

No. Force quitting does not put anything in the Trash. You only need to empty the Trash if you have deleted files or apps you want to permanently remove.
