Important: Apple recommends that you back up the data on your hard disk before
restoring software. Because the “Erase and Install” option erases your hard disk, you
should back up your essential files before installing Mac OS X and other applications.
Apple is not responsible for any lost data.
Installing Mac OS X
To install Mac OS X:
1 Back up your essential files.
2 Make sure your power adapter is connected and plugged in.
3 Insert the Mac OS X Install DVD that came with your computer.
4 Double-click Install Mac OS X.
5 Follow the onscreen instructions.
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.” If you choose “Erase and Install,” you’ll see a message reminding you to use the
Applications Install DVD to reinstall the bundled applications that came with your
computer.
6 When the installation is complete, click Restart to restart your computer.
7 Follow the prompts in the Setup Assistant to set up your user account.
Installing Applications
If you reinstall Mac OS X on your computer and select the “Erase and Install” option,
you must reinstall the applications that came with your computer, such as the iLife
applications.
