4If the power switch doesn’t turn off the computer, unplug your Macintosh.

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, then turn it on again and restart the Macintosh.

Rebuild your desktop regularly

A process known as “rebuilding the desktop” helps your Macintosh keep track of data on your startup disks. Although you usually use the hard disk in your computer as a startup disk, you can also start up from any other disk that has system software installed. It’s a good idea to rebuild the desktop of your startup disks once a month or so.

To rebuild the desktop of a startup disk, follow these steps:

1Hold down the Option and x keys while you start up your computer.

Do not release the keys until you see a message asking whether you want to rebuild the desktop.

2Click OK.
