No doubt most people who’ve switched to Mac computers from the PC world are familiar with the CTRL + ALT + DEL command. It’s used to bring up the task manager, and when pressed twice will reboot the computer.
The Mac equivalent of CTRL + ALT + DEL (Control + Alt + Delete) is Command + Option + Escape. You can use those commands to force-quit frozen apps on the Mac.
Hold down the CTRL and Option keys (located on either side of the space bar) then press the Escape key. This will bring up the Force Quit window showing a list of your open applications. Choose one and press the Force Quit button to immediately end that application.
You can also force a hanging application to quit by right-clicking (CTRL + Click) on its icon in the Dock and choosing “Force Quit” from the context menu.

Macs have a separate key combination to force a reboot: Command-Option-Power. Hold down the Command and Option keys then press the power button to restart the computer.
To force the computer to shut down, hold down the power button for between 5 and 10 seconds.
Forcing a reboot or a shutdown is not advised unless there is no other option. Performing these actions can result in data loss, especially if there are applications running or external storage devices connected. You should first try to correctly reboot or shut down the computer:
