On OSX Sierra, I can no longer select a Bluetooth Audio device for sound output. I can see the Bluetooth head set is connected and I can select momentarily under Sound Output (see attached screenshot). However, within a few seconds, the Bluetooth device de-selects itself and reverts back to Internal Speakers.

A few notes:

  • I have tried a few different Bluetooth headsets and none pair with my Mac. They pair with my iPhone and other Macs so I can rule out an issue with the headphones
  • I have tried deleting Bluetooth plists and re-pairing. That did not work.
  • I have tried deleting plists related to audio with no luck
  • yes, I've rebooted my computer.

This strikes me as an issue with core audio but I'm not sure how to address this without re-installing the entire OS


  • are you sure that the headset doesn't connect to your iPhone instead? I had this problem with one and I had to disable blutooth on my iPhone when I wanted to use it with my Mac, otherwise it would always prefer to connect to the iPhone... – Gio Valerio Apr 4 '18 at 0:19

    Yeah, positive. The bluetooth headset does connect to osx but it loses the connection soon after – mcranston18 Apr 4 '18 at 0:52
  • This is crazy. I have a brand new Yamaha Bluetooth receiver - paiurs perfectly with the iPhone, iPad ... but High Sierra reports that it cannot be used for audio output. Looks to be connected, but iTunes takes a while to try and then fails. Anyone having any good luck? – perkiset Jun 26 '18 at 18:49
  • @perkiset this was a nightmare to fix. There was something out of sync between high sierra, the blue tooth driver, and audio driver. I tried re-installing with no luck. I ended up re-formatting my comp. – mcranston18 Jun 26 '18 at 21:22
  • Did anyone found a solution to this? – Atul Vaibhav Dec 8 '18 at 16:31
