How to Force Quit on Mac
Learn how to force quit frozen apps on a Mac using keyboard shortcuts, the Apple menu, Activity Monitor, and Terminal.
We have stared at a spinning rainbow wheel on our Mac more times than we can count. The cursor turns into that multicolored pinwheel of doom, the app stops responding, and clicking around makes it worse.
Force quitting is the Mac equivalent of pulling the plug on a misbehaving app. It shuts the app down immediately, even if it is completely frozen. You lose any unsaved work in that app, but everything else on your computer keeps running normally.
There are four ways to force quit on a Mac, and knowing all of them means you always have an option even if the mouse stops working or the Dock is unresponsive. The keyboard shortcut is the fastest and the one we use 95% of the time.
This whole process takes about ten seconds once you know the shortcut.
Just your Mac. No additional software or tools required. All four methods use built-in macOS features.
Use the keyboard shortcut (fastest method)
Press Command + Option + Escape simultaneously. A window titled "Force Quit Applications" will appear showing all running apps. Apps that are not responding will say "(Not Responding)" next to their name. Select the frozen app from the list and click the "Force Quit" button. Confirm when prompted. The app will close immediately. This shortcut works even when the mouse is sluggish or the Dock is unresponsive, which is why it is the most reliable method.
Good to know: Memorize Command + Option + Escape. It is the single most useful keyboard shortcut on a Mac for dealing with frozen apps. It works in any situation, even if the screen is partially unresponsive. Think of it as Control-Alt-Delete for Mac.
Force quit from the Apple menu
Click the Apple logo in the top-left corner of the screen. Select "Force Quit" from the dropdown menu. The same Force Quit Applications window appears. Select the frozen app and click "Force Quit." This method requires the menu bar to be responsive, so it does not work if the entire system is locked up. But for a single frozen app where the rest of the Mac is working fine, it is a convenient option.
Force quit from the Dock
Find the frozen app's icon in the Dock at the bottom of the screen. Hold down the Option key on your keyboard, then right-click (or Control-click) the app icon. The context menu will show "Force Quit" instead of the usual "Quit" option. Click it. The app closes immediately. This method is quick if you can see the Dock and the app icon. If the Dock is hidden or unresponsive, use the keyboard shortcut method instead.
Use Activity Monitor for stubborn processes
Open Activity Monitor (search for it with Spotlight by pressing Command + Space and typing "Activity Monitor"). This app shows every process running on your Mac. Find the frozen app in the list. You can sort by name or use the search bar. Select the process and click the X button in the toolbar (the stop sign with an X). Choose "Force Quit" from the dialog. Activity Monitor is the most powerful option because it can kill background processes and system-level tasks that do not appear in the regular Force Quit window. Use this when the normal methods do not work.
Heads up: Be careful about force quitting processes you do not recognize in Activity Monitor. Some of them are system processes that macOS needs to function. Killing the wrong one can cause instability or force a restart. Stick to quitting apps you recognize. If you are unsure about a process, search its name online before force quitting it.
Force restart the Mac as a last resort
If the entire Mac is frozen and no method works (keyboard, mouse, and trackpad are all unresponsive), press and hold the power button for about 10 seconds. The screen will go black and the Mac will shut down. Wait a few seconds, then press the power button again to restart. This is a hard shutdown and should only be used when nothing else works. You will lose any unsaved work in all open apps. macOS will usually recover gracefully on restart, but if you were in the middle of saving a file, that file may be corrupted.
Force quitting is safe to do and does not harm your Mac. It is the intended way to deal with frozen apps. macOS is designed so that one crashed app does not take down the whole system. If the same app freezes repeatedly, that is a sign of a deeper issue. Check for app updates first. If it is up to date and still freezing, try deleting the app and reinstalling it. If the entire Mac is freezing (not just one app), that could indicate insufficient RAM, a failing hard drive, or an operating system issue that needs more investigation. But for the occasional frozen app, Command-Option-Escape is your best friend. Memorize it and move on with your day.
Questions we get asked about this
Answers from experience, not a textbook.
Force quitting is safe for your Mac. It does not damage hardware or the operating system. However, you will lose any unsaved work in the app that you force quit. Files that were already saved before the freeze are fine. Most modern apps (Pages, Word, Google Docs) auto-save frequently, so data loss is usually minimal. The risk is mainly with apps that do not auto-save, like some older versions of creative software.
Common causes include: the app is out of date and has a bug that is fixed in a newer version, your Mac is running low on RAM because too many apps are open, the app's cache or preferences file is corrupted, or there is a compatibility issue with your macOS version. Start by updating the app. If that does not help, try quitting other apps to free up memory. As a last resort, delete and reinstall the app.
Command + Option + Escape is the closest equivalent. It opens the Force Quit Applications window, which is similar to what Control-Alt-Delete does on Windows (opening Task Manager to end unresponsive programs). There is no exact one-to-one equivalent because macOS handles system-level tasks differently, but for the purpose of killing a frozen app, Command + Option + Escape does the same job.
Yes. Finder appears in the Force Quit Applications window. Selecting it and clicking "Force Quit" will relaunch Finder rather than closing it permanently, since Finder is a core part of macOS. This is actually a useful trick if Finder is acting buggy, not showing files, or running slowly. Relaunching it clears its state and often fixes the issue without restarting your entire Mac.
