This article describes several ways to force quit an unresponsive application on a Mac, including keyboard shortcuts, the Dock icon, the Apple icon, and the Activity Monitor.

While you can use the keyboard shortcut Control+Alt+Delete to close an unresponsive application on Windows, the key combination for that action is different on a Mac. As you may have noticed, Macs do not have an Alt key.

The Command+Option+Escape keyboard shortcut is useful if you want to close multiple unresponsive apps.

Use the keyboard shortcut Command+Option+Escape to display the Force Quit Applications window.
