You should easily be able to shut down or restart your Mac unless you are having issues with your Mac. Our articles often suggest “turn it off and turn it back on again” to troubleshoot a variety of macOS hardware and software problems. This means that this advice won’t work for you if your Mac doesn’t shut down properly.
Sometimes you may experience that your computer just won’t shut down gracefully. Sometimes you may notice that your Mac appears to be still working after shutdown (you may see a black screen with a spinning wheel or you may notice that some internal components still remain powered on). Likewise, your Mac may restart itself instead of shutting down. And lastly, you may get error messages saying “[app name] interrupted shut down”.
This issue may affect Mac notebooks and desktops. In this article, we explain how you can force your Mac to shut down. This article further explains what you can do so that this problem does not occur again.

How to shut down your Mac
It is usually very easy to safely shut down your Mac. You can try one of these:
- Click the Apple menu (located in the top-left corner of your screen) and Shut Down.
- Press the power button until you see an alert message saying (don’t press and hold it because you will do a force shutdown) “Are you sure you want to shut down your computer now?” Then click Shut Down or Restart. The placement of the power button depends on the Mac model you have. But every Mac has one.
- You can also use these keys to do this: Command + Option + Control + Eject / Power.
How to shut down a Mac that won’t respond
If your Mac is unresponsive, shutting it down may not be so easy. But you can force your Mac to shut down. This force shutdown may be handy if your Mac freezes or hangs and refuses to shut down normally. However, you should avoid the force shutdown unless you have nothing else left to do. Here is what you can do:
- You give your Mac some more time. It is possible that the issue may resolve itself. Wait a few minutes before doing anything. Go to the Apple menu and Shut Down and wait a few minutes.
- Quit all open apps and then try again. You can quit all apps instantly if you want to. Then try to turn off your Mac.
- Try to end the app which is unresponsive and has caused the freeze. As stated above, you may get a message saying “[app name] interrupted shut down”. Quit this app and then try again. If you cannot quit, force quit the app. Press the Option, Command, and Esc (Escape) keys to open the Force Quit menu. Select the unresponsive app. Then click Force Quit.
If you still could not turn off your Mac, then try this:
- Press and hold the power button until your screen goes black. This may take a few seconds. Then wait for your Mac to fully shut down before you turn it on. Doing so will force your Mac to close and that may cause you to lose unsaved work.
