I have a 2009 Mac Mini I bought new and the CD drive doesn't work. I've never really used it so I don't understand why it won't work. Is there something I must do first to make it work? I always thought you just put in a CD and it takes it. Mine rejects it, blank or program disk, it rejects. Help! I bought a router and it has a CD I must insert in order to get the router to work. Thanks.
