Forcing any Mac to Shut Down

Understand that force-quitting your Mac can cause problems. If you have open programs when you force-quit your Mac, the programs will be forced to close as well, which can cause you to lose unsaved work. In some cases, force-quitting may even corrupt open programs or installers.
1. To be as safe as possible, try to close any open programs before you force your Mac to shut down.

Determine the severity of your Mac's condition. If your Mac is so frozen that you can't interact with any on-screen items or even move the cursor, skip the next two steps.
1. If you can still interact with some of the on-screen items, you may want to try force-quitting the program that's causing your Mac to freeze.

Try force-quitting an application. If your Mac froze after you opened a specific application, you can try force-quitting the application by doing the following:
1. Press ⌘ Command+⌥ Option+Esc to bring up the Force Quit window.
2. Click the program you want to force-quit.
3. Click Force Quit at the bottom of the window.
4. Click Force Quit if prompted.

Try to save any open work. If you've determined that you're unable to force-quit the problematic program, try saving any in-progress work in any responsive programs. You can usually do this by pressing ⌘ Command+S while in the program's window.
1. Since forcing your Mac to shut down will also cause all open programs to close, you may lose unsaved work.
2. Many programs, such as those in the Microsoft Office suite, will save a backup of your work that you can restore upon restarting your Mac.
