Turn off (shut down) your Mac
choosing Shut Down from the Apple menu is really the best way to shut down your Mac
Just as your Mac follows a startup process after it turns on, it follows a shutdown process before it turns off. That process contains automatically quitting all open apps and logging out of your macOS user account.
When your Mac doesn't shut down, try Force Quit to close any apps that aren't responding. In case it doesn’t work, press and hold the power button until the Mac turns off.
When your Mac doesn't turn on
When your Mac doesn't turn on, you should check your power connection, and if you're using a Mac notebook, become sure that its battery has some charge. Moreover you can also try holding down the power button for ten seconds, then pressing the power button again to see if the Mac turns on. Learn more about what to do if your Mac doesn't turn on.
