MacBook Air uses special version of Leopard

This shouldn’t be any huge surprise, but Apple documentation confirms that the MacBook Air uses a specialized version of Leopard.

Apple’s technical documents confirm that the version of Leopard is made exclusively for the MacBook Air.

The Mac OS X 10.5 installation media that shipped with your MacBook Air is designed for use on this computer only and not intended for any other computer. The installer prevents this software from being installed on other Macintosh computers.
