The USB flash drive included with the MacBook Air contains a backup copy of the MacBook Air software. In the event that you need to reinstall this software, you may like to see your user guide (see attachments below). To reinstall Mac OS X, insert the drive and hold down the C key as the computer starts up. To run Apple Hardware Test, insert the drive and hold down the D key as the computer starts up.
