Hello, I am using Parallels with some software that works in conjunction with bluetooth. When Parallels came out they recommended using a BT dongle that is USB based since you could not use the built in BT on the iMac. Well I updated the the last 2 new versions and Parallels just quits out now when I am using the software for the BT. Does the new versions now work with the built in BT and that is why I am getting conflicts and then an unexpected quit issue? Please let me know what you think I should do?
