Just upgraded to Big Sur and on my 2014 MacBook Air the AirPods auto switching doesn’t appear to be working. Works fine between iPad and iPhone on iOS 14.2, however on MacBook Air it comes up with a notification asking to connect. Checked Bluetooth settings and Airpods are set to connect Automatically. Checked Apple support link and doesn’t mentioned any hardware requirements for MacBook Air side. Any else have it working on older Mac hardware?
