Installing the Mac OS
Step 1: Start Up From the Mac OS CD
Before you begin, turn off any security or virus-protection software you have installed on your
computer.
If you have a PowerBook, plug it in and use the Energy Saver control panel to set it so it
doesn’t go to sleep.
Next, start up your computer using the Mac OS CD.
1 Insert the CD in your computer’s CD-ROM drive.
2 Shut down your computer.
3 Turn on your computer while holding down the C key on your keyboard.
Continue holding down the C key until you see the smiling face.
You’ll know you’ve started up from the CD when your computer’s desktop pattern changes to
a light-colored background that says “CD.”
Need help starting up from the CD?
If your computer won’t start up from the CD, or if it doesn’t have a CD-ROM drive, see
“Troubleshooting Information” on page 9.
