Start over

Often you can eliminate a problem simply by clearing the computer’s memory and starting over.

If you can, save any open documents before restarting the Macintosh. 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 x-Option-Esc to quit the program in use when the problem occurred; if this works, you can then save the documents open in other programs before restarting.

To restart your Macintosh, try the following steps:

1If 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 the computer.

2If you can’t choose Restart, hold down the x and Control keys while you press the

Power key (marked with a triangle).

This key combination restarts the computer. (Use this key combination only when you can’t choose Restart from the Special menu.)

3If nothing happens, turn off your computer with the power switch, wait at least 10 seconds, and then turn it on again.
