How to Force Quit an App on a Mac

If you have landed here from the Windows world, the idea is familiar: an app stops responding, the pointer becomes a spinning colour wheel, and you need a clean way to end just that program without restarting the whole computer. macOS gives you four dependable methods, from a one-handed keyboard shortcut to a full process monitor. This guide walks through each one, explains when to reach for it, and shows how to avoid losing unsaved work along the way.

Method 1 — Press Option-Command-Esc (the quickest way)

This is the method to memorise. It works even when the frozen app is filling the screen, and it does not depend on the Dock or the menu bar being responsive.

1. Hold down Option + Command + Esc together. The Force Quit Applications window appears.
2. In the list of open apps, click the one that is misbehaving. An unresponsive app is usually marked (not responding) in red next to its name.
3. Click the Force Quit button.
4. If macOS asks you to confirm, click Force Quit again. The app closes immediately.

You can leave the Force Quit Applications window open while you work — it stays on top so you can end another app if a second one hangs. Close it with the red dot in its corner when you are done.

Method 2 — Use the Apple menu > Force Quit

If you prefer the mouse or trackpad, the same window is one menu away. This is handy when a background app is causing trouble but your menu bar still works.

1. Click the Apple menu (the Apple logo) in the top-left corner of the screen.
2. Choose Force Quit… from the menu. (This opens the same Force Quit Applications window as the shortcut above.)
3. Select the frozen app, then click Force Quit.

Tip: holding Shift while the Apple menu is open changes the entry to Force Quit followed by the name of the front-most app, letting you kill the active app directly. This label varies with which app is in front, so if you don't see it, just use the plain Force Quit… item.

Method 3 — Force quit from the Dock

Every open app has an icon in the Dock, and you can end a specific one right there. This is the most direct route when you know exactly which app is frozen.

1. Find the app's icon in the Dock (an open app shows a small dot beneath it).
2. Right-click (or Control-click, or two-finger click on a trackpad) the icon to open its shortcut menu. A normal menu shows a Quit option.
3. Now hold down the Option key. Watch the menu: Quit changes to Force Quit.
4. With Option still held, click Force Quit. The app closes at once.

A quicker version: right-click and hold the Dock icon to open the menu, then press Option and the same Quit → Force Quit swap happens without a second click.

Method 4 — End a stubborn process in Activity Monitor

Sometimes an app does not even appear in the Force Quit window, or a background process is eating your CPU and fans. Activity Monitor is macOS's built-in task manager — the closest thing to Windows Task Manager — and it can end anything you have permission to touch. Apple's Activity Monitor guide to quitting a process documents the Stop button in the upper-left corner, the red (Not Responding) marker, and the difference between the Quit and Force Quit choices.

1. Open Activity Monitor. It lives in your Applications folder, inside the Utilities sub-folder:

   Applications ▸ Utilities ▸ Activity Monitor

   The fastest way to open it is Spotlight: press Command + Space, type Activity Monitor, and press Return.
2. In the Process Name list, click the app or process you want to end. Unresponsive apps show (Not Responding) in red. If you can't spot it, click the CPU column header to sort by CPU use — a runaway process often sits at the top.
3. Click the Stop button (the octagon with an ×) in the upper-left of the toolbar.
4. Choose one of the two options in the dialog that appears:
   • Quit — the same as choosing File > Quit inside the app. The process quits when it is safe to do so and won't end if that could cause data loss. Try this first.
   • Force Quit — the process quits immediately. If it has files open, you may lose data. Use this only when a plain Quit doesn't work.

If you try to quit a process you don't own — for example a system process — macOS may ask for an administrator name and password. Be cautious here: ending system processes you don't recognise can make macOS unstable until you restart.

Which method should you use?

• A visible app is frozen → Option + Command + Esc. It's the one-shortcut answer.
• You'd rather click than type → Apple menu > Force Quit….
• You know exactly which Dock app is stuck → Option + right-click its Dock icon > Force Quit.
• The app won't show up, or a background process is the culprit → Activity Monitor.

How to avoid losing data

Force quitting is safe for your Mac, but not for your unsaved documents. A few habits keep the damage to zero:

• Wait a moment first. The spinning wheel often clears on its own once the app finishes a heavy task. Give it 20–30 seconds before deciding it is truly hung.
• Save when you can. If any part of the app still responds, press Command + S before force quitting.
• Prefer Quit over Force Quit in Activity Monitor — a plain Quit refuses to end an app if that would lose data.
• Reopen and check. Many Mac apps auto-save or offer to restore documents when you relaunch them. After you force quit, open the app again and look for a recovered version before you assume your work is gone.

When the whole Mac is frozen

If nothing responds — no shortcut, no menu bar, no pointer — the app isn't the only problem. As a last resort, press and hold the power button for about ten seconds until the Mac shuts down, then press it again to start back up. Apple's own instruction is to force a shutdown by pressing and holding the power button until your Mac shuts down, with the warning that you may lose unsaved changes in open documents. This ends every app at once and should only be used when you can't reach any of the methods above, because it closes everything without saving.
