  1. Doesn’t work for me. My Bluetooth connection keeps turning on and off. VERY VERY annoying. I’m so frustrated. It took me 5 minutes write this because of the connection lost.
    Have tried everything off the above.

    iMac Late 2012 Catalina 10.15.7

  2. Thought I tried everything but Bluetooth on my iMac 2017 was still not available. Until I reset the NVRAM!! Works great now… thanks so much!!

    FYI, this began after the latest Big Sur 11.4 update.
