My 1st snag with the Mac Mini. I'm using a sonnet BT adaptor with an Apple BT keyboard. It seems that the signal is causing a ground loop type hum in my headphones. The noise doesn't get any louder with the volume increased but it's always there. I disconnected the Apple KB & connected my Logitech BT KB & the noise was gone. So far the need for audio has been limited so I'm sticking with the Apple KB for now. Anyone else with this prob?
