Every Mac user meets this problem sooner or later. You click the red button, you choose Quit, and nothing happens. The app window stays on screen, the menu stops responding, or you see the spinning beach ball every time you click. It feels as if the whole computer is stuck, but in most cases only one app has frozen, and the rest of your Mac is fine.
The good news is that you almost never need to restart the computer to fix it. macOS includes several ways to close a stubborn app, starting with a gentle quit and ending with a force quit that stops the app immediately. Work through them in order, and you can get back to work in a minute or two, usually without losing anything else.
Quick Answer
Press Command, Option, and Escape together to open the Force Quit window, select the app that will not close, and click Force Quit. If that window does not appear, open Activity Monitor, select the app, click the X button, and choose Force Quit. Save work in your other apps first, because a force quit loses unsaved changes inside the frozen app only.
First, Try the Normal Ways to Quit
Before forcing anything, give the app one more chance to close cleanly. A normal quit lets the app save its state, close its files properly, and warn you about unsaved work. A force quit skips all of that.
Start by clicking on the app window to make it the active app. Then try these gentle options:
- Press Command and Q, the standard keyboard shortcut for quitting the active app.
- Or click the app name in the top-left menu bar and choose Quit from the bottom of the menu.
- Or right-click, or Control-click, the app icon in the Dock and choose Quit.
- Wait at least ten seconds. An app that is finishing a large save, a print job, or an export can look frozen when it is simply busy.
That pause matters. Video and photo apps often need extra seconds to finish writing a large file, and force quitting then can corrupt it. Also check for a hidden dialog box asking whether to save a document, sitting behind another window. Press Command and Tab to cycle through apps and answer it.
How to Force Quit From the Force Quit Window
The Force Quit Applications window is the fastest and safest tool for this job. It lists every app that is running and even marks the ones macOS believes have stopped responding.
- Press Command, Option, and Escape at the same time. On some keyboards the Option key is labelled Alt.
- In the window that appears, look through the list of open apps. A frozen app is often marked with the words Not Responding in red.
- Click the name of the app to select it.
- Click the Force Quit button, then click Force Quit again in the confirmation message.
- Wait a few seconds. The app window should disappear and its icon in the Dock should lose the small dot that shows it is running.
If the shortcut does not open the window, use the Apple menu instead. Click the Apple logo in the top-left corner and choose Force Quit. The same window appears, and you can continue from step two. Apple describes both routes in its official Apple support guide on how to force quit an app on Mac, which is worth bookmarking if this happens often.
Once the app has closed, wait a few seconds before reopening it. If it offers to restore documents from before the freeze, accept. Many apps keep a recovery copy, so you may get back more work than expected.
How to Force Quit Using Activity Monitor
If the Force Quit window will not open, or the frozen app does not appear in its list, Activity Monitor gives you a stronger option. It shows every process on your Mac, including background helpers that belong to the stuck app.
- Press Command and Space to open Spotlight, type Activity Monitor, and press Return. You can also find it in Applications, then Utilities.
- Click the CPU tab and find the app in the Process Name list. Use the search box in the top-right corner if the list is long.
- Click the process name to select it, then click the X button in the toolbar at the top of the window.
- Choose Quit first if the button is offered. If the app ignores it, repeat the steps and choose Force Quit.
Select the right process. Some apps run helpers with similar names; quitting the main app is usually enough, because helpers close with it. Avoid quitting processes you do not recognise. For more help, see our guide on how to force quit a frozen app on a Mac.
Other Options When an App Still Will Not Close
Occasionally an app is so stuck that even Activity Monitor struggles, often because the whole interface is sluggish. A few more options remain before you consider restarting.
Use the Dock With the Option Key
Hold the Option key and right-click the app icon in the Dock. The Quit option changes to Force Quit. Click it and the app closes without any extra windows. This is handy when the pointer still works but menus are slow.
Quit the App From Terminal
Terminal can stop an app by name. Open Terminal from Applications, then Utilities, type killall followed by the app name in quotes, and press Return. Only use this if you know the exact name, because it closes every process with that name. If unsure, stick with Activity Monitor.
Log Out of Your Account
As a last step before restarting, log out from the Apple menu. macOS will try to close every app in your account. Clear the option to reopen windows when logging back in, so the frozen app does not return and freeze again.
What to Do After the App Has Closed
Closing the app solves the immediate problem, but a few quick checks reduce the chance of it happening again in the middle of important work.
- Reopen the app and check your work. Look for recovered documents in the app’s recent files list or in a Recovered folder, and save a fresh copy straight away.
- Update the app. Freezes are often bugs that the developer has already fixed. Check the app’s update option or the Mac App Store.
- Update macOS. Go to System Settings, then General, then Software Update, and install any update that is waiting, following the steps Apple sets out for updating macOS on your Mac.
- Check your free disk space. A nearly full startup disk can make apps hang. Aim to keep at least ten percent of the disk free.
- Note what you were doing. If the app freezes during the same action every time, such as opening one particular file, that file may be damaged. Try a different file to confirm.
Common Mistakes and Useful Tips
The biggest mistake is holding the power button as a first response. A forced shutdown stops everything at once, including apps that were saving files in the background, and it can leave the system in a messy state. Keep it as the true last resort, for when the screen, pointer, and keyboard have all stopped responding for several minutes.
Another mistake is force quitting the Finder to fix an unrelated app. The Finder does have a Relaunch option in the Force Quit window, and relaunching it is safe when the desktop itself is frozen, but it will not fix a frozen word processor or browser.
A helpful tip is to save early and often in an app that has frozen once, using Command and S and any auto-save feature it offers. If one app freezes every day, reinstalling a clean copy or contacting the developer is better than force quitting forever.
Conclusion
An app that will not close rarely means your Mac is broken. Try a normal quit and a short wait first, then use Command, Option, and Escape to force quit, and fall back on Activity Monitor if you need more control. You will lose only the unsaved work inside the frozen app, and everything else keeps running. Afterward, update the app and macOS, check your disk space, and note what triggered the freeze, so the same problem is far less likely to interrupt you again.
Frequently Asked Questions
Will force quitting an app delete my files?
No. Force quitting does not delete saved files from your disk. You may lose changes that were never saved inside that app, which is why it helps to try a normal quit first. Many apps also keep recovery copies and will offer them when you reopen the app.
What is the keyboard shortcut to force quit on a Mac?
Press Command, Option, and Escape together. That opens the Force Quit Applications window, where you can select the frozen app and click Force Quit. It is the Mac equivalent most people look for when they move from a Windows computer.
What should I do if the whole Mac is frozen, not just one app?
Wait a few minutes first, because the system may be finishing a heavy task. If the pointer will not move and no shortcut works, press and hold the power button until the Mac turns off, then turn it on again. Use this only as a last resort, since it stops every app at once.
Why does the same app keep freezing after I reopen it?
Repeated freezing usually points to a bug, a damaged preferences file, a problem document, or an add-on that no longer works with your version of macOS. Update the app, try opening it without the problem file, and remove old plug-ins. If it still freezes, reinstall the app.
Is it safe to force quit apps often?
An occasional force quit is safe and is a normal part of using a computer. Doing it every day to the same app is a sign of a deeper problem worth fixing, because each force quit risks losing unsaved work and, rarely, can leave a file the app was writing in an incomplete state.
