The MacBook Airs and newer Mac minis and the Retina MacBook Pros all have the ability to use DVDs and CDs shared over the network from the optical drives on the other Mac models. Now say your optical drive goes out on a Mac of yours and you don’t have time or funds to fix it and you have another computer that has a working drive. You can enable the Mac with the bad drive to utilize the sharing feature as well. Even though this remote disc sharing feature isn’t configured to work out of the box on the other Macs, it can be unlocked on any Mac running 10.5 and above with the following steps.
Once both those are done restart your Mac.
Back on the Mac with the faulty drive, open Finder and notice how Remote Disc is now listed under Devices in the sidebar. Click here and your shared host device will appear. Stick the disc in the other computer and the CD or DVD and its content should be mounted in Finder just like it was in your Mac’s own optical drive. You can not watch movies this way, but you can install software, view and copy files, etc.
