iMac automatically sending sound to my iPhone via Bluetooth
I turn on Youtube on my iMac and then the iMac turns on Buetooth, so the sound no longer comes from my Bose speakers, but goes to my iPhone which happens to be connected to my hearing aids. This occurs without my touching settings. If I reset, the problem recurs.
