Hey all, I had a terrible bluetooth problem on my Mac Pro, as I read that others have as well. I originally fixed this by purchasing a cheap Kinivo bluetooth adapter that I plugged in via USB to my keyboard. It worked great! Only problem is that I just updated to Mavericks from Snow Leopard (skipped Lion altogether) and now my Bluetooth mouse problem is back! It appears as if the bluetooth adapter isn't registering anymore or something? Before, after a restart, I would get an error message saying no bluetooth devices could be found. Then a secondary pop-up (I believe from Kinivo) would say "Magic Mouse is requesting to pair" or something like that, and then it would connect right away. I'm not getting either of those messages now which leads me to believe that perhaps the bluetooth adapter is no longer being recognized and it's reverting back to the internal bluetooth adapter in the tower. Please help! Thank you!
