I've had the annoying issue of not being able to pair with bluetooth devices on my laptop unless I restart it. This happens for multiple headsets which all pair without issue on other devices and on this laptop as well after the restart.

Some of the pairing behavior includes:

  • I click the device to pair. The macOS ui shows the device as paired and the device says "bluetooth connected". The headset doesn't show as an audio output device and after a few seconds the bluetooth disconnects
  • With another headset, I click to pair the device and it either loads for a while before failing or connects and immediately disconnects.

I've tried

  • all the reset options under the bluetooth menu shown by pressing option + shift
  • stopping the audio daemon with sudo killall coreaudiod
  • clearing the nvram
  • sudo kextunload /System/Library/Extensions/AppleHDA.kext + sudo kextload /System/Library/Extensions/AppleHDA.kext

I'm not sure what to do to troubleshoot this issue. I've tried looking at the logs in console when trying to connect a headset and it fails, but I'm not sure what exactly to look for there.

I'm using a 2019 Macbook Pro on macOS Big Sur 11.5.2.

  • @Volsk if you have android file transfer installed try quitting that process when this happens. Worked for me :)

This happened again and seems to have been fixed by stopping the "Android file transfer" process using Activity Monitor as suggested here: https://discussions.apple.com/thread/8631469

edit: the issues connecting happened again but stopping Android File Transfer didn't fix it. Leaving this answer up in case it works for anyone
