Step 2: Restart your computer
Often you can eliminate a problem simply by restarting your computer, which clears the computer’s memory.
To restart your Macintosh when you are having trouble, try the following steps:
1If you can, save any open documents before restarting.
If your system is frozen and does not respond to anything you do, or if you have a “bomb” message on the screen, saving may not be possible. You can try pressing
2If you can, choose Restart from the Special menu or from the dialog box that’s on screen.
Dialog boxes contain messages from the computer. If something goes wrong, a message may appear on the screen asking you to restart.
3If you can’t choose Restart, press the Power key (marked with a π) on the keyboard.
Click Restart in the dialog box that appears.
4If the Power key doesn’t work, hold down the x and Control keys while you press the
Power key.
This key combination restarts the computer. (Use this key combination only when you can’t choose Restart from the Special menu or restart the computer using the Power key.)
5If your computer still doesn’t restart, press the power button on the front of the computer to turn it off, wait at least 10 seconds, and turn it on again by pressing the Power key on the keyboard.
If you suspect that the problem is with other equipment, such as a printer or an external hard disk that’s attached to your computer, turn that equipment off for 10 seconds or longer while your computer is off, then turn the equipment on again and restart the Macintosh.
