Good Afternoon Everyone, My buddy got a new Macbook Air and we were trying to get Remote Disc to work. As the instructions state you should be able to turn it on with System Preferences>Sharing>Check "DVD or CD Sharing" Well, I do not have the option to click DVD or CD Sharing. The Apple Support site says to download a file if the option is not available but when I do download it and try to install, it says that my computer has a newer version of the software already. Anybody have any idea how to get this working? We both have late 2011 Model Air's running OSX 10.7.3. Please let me know if I can provide anymore useful information to help get this solved. Thanks in advance!
