Reminder: Back up

If you didn’t back up your computer’s hard disk as described in Chapter 1, remember to do so soon. You will need the backup copy if you ever need to reinstall system software.

Reinstalling system software

System software is the set of programs and other files that your computer uses to start itself up, keep track of your files, and run the application programs you use. When you turn on your computer, it looks for a disk that contains the system software, which is always in a folder called the System Folder. Any disk that contains a System Folder with system software inside it is a startup disk. The startup disk is usually the hard disk that’s inside your computer, though another hard disk or a floppy disk can also be a startup disk.

If your Macintosh cannot find a startup disk, it displays this icon in the middle of the screen:

If you see this icon, you need to reinstall system software on your computer’s internal hard disk from a backup copy. See the section on restoring information on your hard disk in Chapter 8.
