Please help or tell me where to post my query.... On an early 2009 Mac Pro 5,1 running 10.13.6 High Sierra with an upgraded bluetooth module that worked just fine for many years. But when I re-formatted a hard drive and tried to run a later OS, something happened and now I have no Bluetooth whatsoever. Been this way for over 2 years now, but when I opened Bluetooth Explorer 4.4.0 it kept trying to initialize Bluetooth Support and failing. It repeated the following message:
