It sucks that this happened to you, is it a new macbook pro the one with Retina Display that might be the problem. I bought mine three years ago and use it with my Mac Tower, I never had any of the problems you describe. Worked great not only with FCP 6 also worked amazing with my Avid Media Composer 4. Not sure if its the new operating system or might not be compatible with FCP 7, honestly has been a great Deck for me and was supprise that you had such a bad experience with it.
