I've just installed Ubuntu 20.04 on my 13 inch 2015 MacBook Pro. When I go to the Bluetooth section in Settings, I can see my wireless headphones listed. The headphones are in their pairing mode, but when I click it on list it never connects. I've tried with three different sets of Bluetooth headphones (Airpods Pro, Airpods, and Bose QC35). What should I do to get my laptop to connect to Bluetooth devices? I know that Bose QC35 headphones work because I've used them with my desktop running 20.04.
For weird problems like not being able to connect to Bluetooth devices from your MacBook Pro, sometimes the solution is just to reset the SMC. Once I did that and restarted I was able to connect my headphones. This resulted in stuttering audio through my headphones, which I've "fixed" (fingers crossed) by restarting the bluetooth service. So everything is working well now. :)
