How Do I Use Remote Disc With My MacBook Air And Another Mac?
Before accessing a CD/DVD on your MacBook Air, you have to setup the other Mac for DVD or CD sharing. On that Mac, go to System Preferences > Sharing and make sure the "DVD or CD Sharing" box is checked. Insert the CD/DVD you would like to share and then boot up the MacBook Air. Open a Finder window and you should see "Remote Disc". Double-click on the drive and select "Connect". You may have a dialog to confirm on the other Mac before you can access the media on the MacBook Air.
