Sometimes a Mac app freezes up and you have to kill it. Well, not actually kill it, but you may have to force it to quit so you can relaunch it.
Here’s how you use Force Quit an application in macOS:
- Choose Force Quit from the Apple () menu, or press Command-Option-Esc.
- Select the app in the Force Quit window.
- Click Force Quit.
Of course, you should try quitting it in the normal way first by choosing Quit from the app’s menu in the menu bar, or press Command (⌘) – Period (.) to cancel any open dialog box.
You can also use the Activity Monitor app.
- Launch it from the Utility folder on your hard drive.
- In the “Process Name” list, select the app or process you want to quit. An unresponsive process is marked with “Not Responding.”
- Click the Force Quit button (an “x” in a circle) in the upper-left corner of the Activity Monitor window (or use the Touch Bar on Mac laptops that have one).
Choose one of the following options:
- Quit: This is the same as choosing File > Quit within an app.
- Force Quit: The process quits immediately. If the process has files open, you may lose data.
