Big Sur bluetooth problems

Since updating to Big Sur I'm having trouble with my bluetooth devices. They (mostly) connect OK, but I cannot play sound to my bluetooth speakers or headphones. The issue occurs on both of the Macs that I have updated so far.


Any advice?

MacBook Pro 15″, macOS 11.0

Thank you very much, this solved the problem on both my iMac and my MacBook Pro.


Here is what I did:


  1. Open a folder window and in the "Go" menu from the toolbar at the top of the screen click on "Go to Folder..."
  2. When prompted enter the following: /Library/Audio/Plug-ins/HAL/
  3. You will be taken to the "HAL" folder in Finder, which in my case contained only one subfolder, called "InstantOn.driver". Delete this folder, entering your password as confirmation when prompted.
  4. Restart your Mac and hopefully everything will now work fine.


Poor show, Apple!
