At some point we have all been there. Your app won’t close. It won’t move. It won’t react to the mouse. It just stares at you, daring you to make it work. Force Quite seems to be your only option. It is a much better option than the one we had in the old days – restart the machine.
First Option.The most common way to Force Quit is the option built into Finder. Choose the Apple Menu → Force Quit. The frozen app will most likely be highlighted in brown and have the words “force quit” next to them. Move the cursor up to the appropriate app, click your mouse, and it will be closed.
As you can see from the image, you can also access this option by selecting Command-Option-Escape.
Second Option. Some programs, including the Dock, don’t show up in the Force Quit menu noted in the first option. Same thing can be true with certain utilities. You still can implement a forced quit. It just takes a few more steps.
Open the Activity Monitor program. Spotlight → Activity Monitor or Go Menu → Applications → Utilities → Activity Monitor.
Click on any program on the list and when a dialog box pops up, click Quit to force quit it.
