Hi (all 13 inch models) i used macbook pro 2013, no audio issue upgraded to 2015, used it for years, no audio issues waited for escape key to get back, and got 2020 (4 ports) running OS 10.15.6 (19G2021). had it on 10.15.4 too so basically i upgraded (not to mention $$$) to a bug? for once, can apple get everything right? Rest in peace Steve, Rest in peace Apple ? only if I was not for the track pad and i was not an iOS developer :-( really starting to get ****** since 2016 i know no one is going to even bother to take a look at the issue by my post here, its my attempt to get it out of my system. thats what the forums are for now a days.
