New feature supports MacBook Air.

Have you peeked in the Sharing preferences pane since updating to Mac OS X 10.5.2? Take a look and you’ll see a new option right at the top of the Service list: DVD or CD Sharing. This option, once enabled, makes it possible to share your computer’s optical drive with a MacBook Air via the Remote Disc feature.

This feature makes it possible to use another computer’s optical drive to run installation software on DVD or CD on a MacBook Air, which lacks its own optical disk.

Once enabled, the DVD or CD Sharing feature has one option with a check box: Ask me before allowing others to use my DVD drive. Turning on this option ensures that you approve any shared use of the disk.
