I also use a MacBook Air with the new M1 chip running Aurdirvana Studio, no issues at all and sounds great. I think your comment "Apple is on a war path with Audirvana and is blocking them out" is misleading. You probably have a software or settings issue. Try upgrading the OS from 11.6 to 12.1.
Audirvana Studio vs. Apple OS 11.6: what's going on?
I made the mistake and automatically "upgraded" my MacBook Air (Apple M1 chip) to the latest OS (11.6) and at the same time "upgraded" my Audirvana subscription to the latest version (Audirvana Studio). The two do no longer talk to each other, and I can no longer play my iTunes library (>1000 entries). I also can no longer connect to my DAC (MSB Platinum IV) via USB. My old Macbook running the old Audirvana version had no problem and sounded great! Something tells me that Apple is on a war path with Audirvana and is blocking them out. Has anybody had similar experiences? And if so, how did you deal with it?
