just bought a used 3rd gen shuffle off ebay. tried it out on the macbook pro and itunes told me it was corrupt and to restore it. i did multiple times and it still failed. i even reformatted the ipod's hd to every different format and still nothing. then i just restored once more and STILL itunes deemed it corrupt. for the hell of it i walked over to the family windows computer and lo and behold it works fine. took it back to the mbp and still corrupt. i just want to know what is necessary to make the ipod work on the mac. i have heard of many cases of an ipod working with mac and not windows, but never the opposite. any help would be much appreciated.
