I have the Logic Pro upgrade that allows update from Platinum/Gold 5 or 6. I found someone with Logic Platinum 5 however the dongle is blue. We are unsure if this indicates that it is only for PC. The discs provided with the software package are for both PC and Mac. I am wondering if someone with more experience with pre-apple emagic can clue us in as to whether there was any difference between dongles. I've searched google but it's so hard to construct a query that doesn't include so many other topics unrelated to my issue. Any help would be much appreciated. Cheers, Aaron
