Restarting a computer that’s already on
You need to restart your computer—turn it off and back on again—when you
want to make certain changes to settings, use a newly installed system
software file, or start up the computer using a different disk.
You may also need to restart if you see a “system error” message on the
screen (indicating a temporary software problem). In this case, use the
trackpad to click the Restart button that appears.
Follow these instructions to restart your computer:
1Press and hold the Power key for about two seconds.
2Click the Restart button.
You can also do this to restart:
m Choose Restart from the Special menu.
If the Special menu does not appear in the menu bar, you’re working in the
wrong program. Choose Finder from the Application menu at the far-right
end of the menu bar.
