Chapter 3 Problem, Meet Solution 47
Before you install Mac OS X:
1 Back up your essential files.
Apple recommends that you back up the information on your hard disk before
restoring software. You can do this by connecting the MacBook Air SuperDrive and
burning important information to DVDs or CDs, or by attaching an external hard drive
to the USB port on your MacBook Air. Apple is not responsible for any lost data.
2 Make sure your power adapter is connected and plugged in.
To install Mac OS X using a partner computer:
1 Follow the procedure for using Remote Install Mac OS X beginning on page 45.
2 Click Continue in Remote Install Mac OS X.
Status messages appear on the other computer’s screen during installation.
3 Click Customize to select what to install, or click Install to perform a basic installation.
4 Follow the onscreen instructions, selecting your MacBook Air as the destination volume
for installation.
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.” This option erases your MacBook Air hard disk, so be sure you’ve backed up
important information. If you choose this option, you’ll need to use DVD or CD Sharing
and the Applications Install DVD to reinstall the bundled applications.
5 Click OK in Remote Install Mac OS X, and, when installation is done, click Quit to exit
Remote Install Mac OS X.
