When I pair my bluetooth headphones (Bose QC 35) to my MBP running macOS Mojave, they sometimes disconnect a few seconds later. I try turning them off and on again, turning off bluetooth on my phone (in case it's competing for a connection or something), but none of that helps. The only solution I've found is to restart my computer which is really not ideal.

Ideally I'd like to find the cause of this, but it would also be really helpful to find a workaround. For example, is there some kind of driver I could try restarting without having restart my whole computer?

  • @IulianOnofrei that would be an excellent question on Ask Different Meta – bmike Feb 8 at 1:18

Try resetting the Bluetooth module.

Shift-Option click the BT menu bar item > Debug > Reset the Bluetooth module.

  • For me the reconnection of the headset from Bluetooth -> Bose QC35 -> Connect is enough. – onik Feb 20 at 15:03

The Bose Connect app on iPhone is my go-to for this situation. Typically the issue is that my QC 35's are connecting to other devices (Apple TV, iPad, etc.) instead of my Mac and the app allows me to disconnect the headphones from that device and then connect them to my Mac (all from within the app!).


In my case I had my headphones connected to charge via the keyboard despite the lack of power. I think this may have confused the blutooth as once I connected back to the keyboard and disconnected after the low power warning went away then it could connect as normal?

I hope this helps someone else.

  • I think the error has something to do with the headphones connecting to charge via USB at some point. If anyone else can confirm let me know, but I seem to be able to re-create the error now at will. – Joseph Astrahan Feb 20 at 6:07
