Reinstalling the Software That Came with Your MacBook Pro
Use the software installation discs that came with your computer to reinstall Mac OS X
and any applications that came 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 MacBook Pro:
1 Back up your essential files.
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.
2 Make sure your power adapter is connected and plugged in.
3 Insert the Mac OS X Install Disc 1 that came with your computer.
4 Double-click Install Mac OS X and Bundled Software. To install only the applications
that came with your computer, double-click Install Bundled Software Only.
Note: To install iCal, iChat AV, iSync, iTunes, Safari, and the iLife applications,
double-click Install Mac OS X and Bundled Software.
5 Follow the onscreen instructions.
6 After selecting the destination volume for installation, continue following the onscreen
instructions. Your computer might restart and ask you to insert the next Mac OS X
installation disc.

click Options in the Select a Destination pane of the Installer, and then select Erase
and Install.
