Force an app to close on your Mac
Generally, you shouldn't need to use Force Quit unless you can't close an app normally.
The Finder is an app that your Mac keeps open, so there isn't an option to quit or close this app. If the Finder becomes unresponsive, you can use Force Quit to relaunch it. Select Finder in the Force Quit window, then click Relaunch.
If none of your apps are responsive, you can force your computer to restart.
