Reinstalling the Software That Came With Your Computer
Use the software installation discs that came with your computer to reinstall Mac OS X
and any applications that came with your computer, as well as to install Mac OS 9
support for running the Classic environment (if you want to use Classic applications
with your computer).
Important: Apple recommends that you back up the data on your hard disk before
reinstalling software. Apple is not responsible for any lost data.

Installing Mac OS X and Applications

To install Mac OS X and the applications that came with your computer, follow
these steps:
1Back up your essential files.
Because the Erase and Install option erases your destination disk, you should back up
your essential files before installing Mac OS X and other applications.
2Make sure your power adapter is plugged in.
3Insert the Mac OS X Install Disc 1 that came with your computer.
4Double-click Install Mac OS X and Bundled Software.
5Follow the onscreen instructions.
6After selecting the destination disk for installation, continue following the onscreen
instructions. Your computer might restart and ask you to insert the next Mac OS X
installation disc.
Note: To restore Mac OS X on your computer to the original factory settings, click
Options in the Select a Destination pane of the Installer, and then select Erase and
Install.
After selecting the destination disk for installation, continue following the onscreen
instructions for a basic installation of Mac OS X. To install custom applications, click
Customize, click the triangle next to the application, and select the application that
matches your language.
