Reinstalling the Software That Came with Your Mac mini
Use the software installation discs that came with your Mac mini to reinstall Mac OS X
and any applications that came with your computer. You can install Mac OS X without
erasing the target volume, which saves your existing files and settings, or you can erase
the volume first, which erases all your data and leaves the computer ready for you to
reinstall Mac OS X and applications.
Important: Apple recommends that you back up the data on your hard disk before
restoring software. Apple is not responsible for any lost data.
