Sure, i’d be delighted to help you, mandarcy. Bluetooth performance in the Mac Pro can be subject to interference, especially 2.4 Ghz wifi, plus having the BLuetooth antenna in the case doesn’t help.. you might get somewhat better Bluetooth performance by changing which antenna goes to the bluetooth antenna socket on the board, eg, the antenna that’s labelled ‘bluetooth’ should be disconnected and either #1 or # 2 connected to the Bluetooth socket… that being said, you can get a card from OSXwifi.com which will update both the Wifi and Bluetooth to the latest version.. you can also get a pci-E card which plugs into one of the pci-E slots, works with Mac OS X and has antennas that stick out of the back of your Mac Pro.. and upgrades both the Wifi and Bluetooth( available on Amazon) ..i can’t say with any certainty which one works the best.. but either one should be helpful… the os x wifi one is a little pricey, and you may have to do some work.. but that’s up to you… i can tell you, though, with 100 % certainty that installing a wifi and a bluetooth board in there, including finding and attaching the antennas, is a royal pain in the butt, but it’s do-able if you’re patient and have a somewhat light touch, which i don’t really have, but I still got it done successfully.

good luck to you
