The fastest way to close a frozen app
When a Mac program stops responding, the quickest fix is to use Force Quit, which closes the app when ready without saving. Press Command + Option + Esc to open the Force Quit window, click the frozen program in the list, then click Force Quit. The app will close in seconds, and you can reopen it normally.
This keyboard shortcut works on any Mac running any recent version of macOS. You do not need to restart your computer or force-quit other programs — only the one you select will close. After the app shuts down, your other work stays open and unsaved.
If the Force Quit window itself does not appear, or if the keyboard shortcut does not work, your Mac may be severely frozen. In that case, hold the power button for 10 seconds to force a shutdown, then turn the Mac back on normally.
Key Takeaways
- Press Command + Option + Esc to open Force Quit, select the frozen program, and click Force Quit to close it when ready.
- Force Quit closes only the program you select and does not affect other open apps or unsaved work in them.
- If Force Quit does not respond, hold the power button for 10 seconds to shut down your Mac, then turn it back on.
- After force-closing an app, check Activity Monitor to see if the program is still running or using CPU in the background.
- Repeated crashes in the same program usually mean the app needs an update or your Mac needs more free storage space.
Using Activity Monitor for more control
If Force Quit does not work or you want to see why a program is frozen, open Activity Monitor instead. Go to Applications > Utilities > Activity Monitor, or press Command + Space, type "Activity Monitor", and press Enter. The window shows every running program and how much CPU and memory each one is using.
Find the frozen program in the list — programs that are not responding usually show "(Not Responding)" next to their name. Click it once to select it, then click the X button in the top left corner of the window. A dialog will ask whether to force-quit; click Force Quit. The program will close.
Activity Monitor also shows you which programs are using the most resources. If a program regularly uses 80% or more of your CPU or fills your memory, that is often why it freezes. Closing other background programs or restarting your Mac can help, but the real fix is usually updating that program or freeing up storage space on your drive.
What happens to your unsaved work
When you force-quit a program, any work you did in that program since the last save is lost. The program closes without writing anything to disk. Other programs you have open are not affected — if you were working in a document in another app, that work stays open and unsaved in that app.
Some programs like Google Chrome, Microsoft Word, and Apple's own apps have recovery features that reopen your work the next time you launch them. When you restart the program, it may show a recovery window asking whether to restore the last session. Click "Restore" to get your work back. Not all programs have this feature, so do not count on it.
To avoid losing work, save your files regularly while you work. If a program starts to freeze, try saving first — sometimes a frozen program will still respond to Command + S even if the interface looks stuck. Wait a few seconds after pressing save before force-quitting.
When to force-quit versus waiting it out
A program that is briefly unresponsive sometimes recovers on its own. If an app freezes for just a few seconds, wait 10 to 15 seconds before force-quitting — it may come back. If it is still frozen after 15 seconds, or if the spinning wheel keeps spinning for more than a minute, force-quit it.
Some programs freeze because they are processing a large file or downloading data. If you know the program is working on something big, give it a minute or two. You can check Activity Monitor to see if the CPU is still active — if the program is using 5% CPU or more, it is still working. If CPU is at 0% and the program says "Not Responding", it is truly stuck and will not recover.
If a program freezes every time you do the same thing — like opening a specific file or clicking a certain button — the program likely has a bug or is incompatible with your version of macOS. Force-quit it, check for updates in the App Store or the program's website, and install any available updates before trying again.
Preventing programs from freezing in the first place
Most freezes happen because a program is out of date, your Mac is low on storage space, or too many programs are running at once. Keeping your programs updated is the single best prevention — updates fix bugs that cause freezes. Go to the App Store, click Updates in the top menu, and install any waiting updates. For programs you bought outside the App Store, check their own menus for update options.
Free up storage space if your drive is nearly full. A Mac that has less than 10% free space runs slowly and programs freeze more often. Go to Apple menu > About This Mac > Storage to see how much space you have left. If the bar is mostly full, delete large files you no longer need, empty your Trash, or move old files to an external drive.
Close programs you are not using. Each open program uses memory, and when your Mac runs out of memory, programs slow down and freeze. Check Activity Monitor to see which programs are using the most memory, and close the ones you do not need right now. Restarting your Mac once a week also clears out memory and often prevents freezes.
Force-quit on different Mac models and macOS versions
The Command + Option + Esc shortcut works the same way on every Mac — MacBook, iMac, Mac mini, Mac Studio, and Mac Pro. It works on macOS Monterey, Ventura, Sonoma, and all recent versions. If you have an older Mac running an earlier version of macOS, the shortcut still works, though the Force Quit window may look slightly different.
On very old Macs or if the keyboard shortcut fails completely, you can also force-quit through the Apple menu. Click the Apple logo in the top left corner, hold Option, and click "Force Quit". This opens the same Force Quit window as the keyboard shortcut. The result is identical.
If your Mac is so frozen that even the Apple menu does not respond, the only option is to hold the power button for 10 seconds. This forces a complete shutdown. Wait a few seconds, then press the power button again to turn your Mac back on. This is a last resort and should not be your first choice, but it always works.
Frequently Asked Questions
Does force-quitting a program damage my Mac?
No. Force-quitting closes a program the same way restarting your Mac does — it is a normal operation. Your Mac is designed to handle it. The only downside is that unsaved work in that program is lost. Everything else on your computer is unaffected.
Will force-quitting delete my files?
Force-quitting closes the program but does not delete any files. Files you saved before the freeze stay on your Mac. Only unsaved work in that program is lost. Files in other programs are not touched.
Why does the same program keep freezing?
Repeated freezes in one program usually mean the app is out of date, has a bug, or is incompatible with your macOS version. Check for updates in the App Store or the program's website. If updates do not help, try uninstalling and reinstalling the program. If it still freezes, the program may not work well on your Mac.
Can I force-quit multiple programs at once?
You can force-quit them one at a time through the Force Quit window or Activity Monitor. Open Force Quit, select the first program, click Force Quit, then repeat for the next one. If your Mac is so frozen that nothing responds, hold the power button to shut down everything at once.
What is the difference between closing an app normally and force-quitting?
Closing normally lets the program save its state and any unsaved work, then shuts down cleanly. Force-quitting skips all that and closes when ready. Use normal close when the program responds. Use force-quit only when the program is frozen and will not respond.
