Mac computers

How can you shut down your Mac when the system doesn't seem to want to turn off? Well, here are four ways (as documented in more detail by MacObserver)

1. The power button
2. A keyboard shortcut
3. The Apple menu
4. Via the terminal

The power button

• Press and hold the Power button for 10+ seconds and the system will turn off. Release the power button and wait a few seconds. Press the power button briefly and the system will turn back on.

A keyboard shortcut

• Press and hold the four keys Control + Option + Command + the Power button for a moment, then release them all at the same time. This key combo attempts to safely shut down all running applications, then shuts the machine down.
• Hold Control + Command + the Power button until the system shuts off. Release all the keys and wait a few moments. Press the power button again to turn the computer back on.

The Apple menu

1. Click on the Apple menu at the top left of the screen
2. Select Shut down...
3. Once the computer turns off, press the Power button to turn it back on

Via the terminal

1. Press Control + Space to open the Mac Spotlight Search feature
2. Type Terminal and press enter to open the terminal
   • Alternatively, you can choose Terminal from the Applications -> Utilities menu
3. At the terminal prompt, type the following (the % mark is the terminal prompt - type everything following that):
   • % sudo shutdown -r now
   • Press Enter
4. After the computer powers off, press the Power button to restart the computer.
