Installing or 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. System software is kept in the System Folder. When you turn on your computer, it looks for a startup disk, which is a disk that contains the system software. 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.

When should you install or reinstall system software?

Your Macintosh came with all the necessary system software installed on its internal hard disk, so you don’t need to install system software on that disk unless you encounter software problems.

If you have a new hard disk or a newly initialized hard disk that doesn’t contain system software, or if you want to upgrade to a more recent version of system software on a hard disk, you’ll need to install system software. See the next section, “How to Install or Reinstall System Software.”

If your hard disk already has system software installed on it but there is a problem with the disk or the software, you may see this icon in the middle of the screen:

If this icon appears, first try testing your startup hard disk and repairing any damage. To do this, follow the instructions in “Repairing a Damaged Disk” earlier in this chapter. If repairing the disk doesn’t help, you may need to reinstall system software.
