Mac Error - Audio System Unstable - Unable to Shutdown Audio Output subsystem

[JJGuy]

@JJGuy - what is your interface, and your OS version? Are you on a Gold service plan (provides 1 to 1 tech support)?

I'm using Catalina on an Intel CPU Mac Mini, & my interface is a MOTU 828es. I'm not having any problems with the latest JK client

I'm on a MacBook Pro 1.4 GHz Quad-Core Intel Core i5, Big Sur 11.2.3. the Mac it's self is a 2020 model
My interface is a Steinberg UR 22 C
I sent an email to tech, but haven't heard back anything yet, but is there a different way, like a online chatting one on one

I don't know of any other method to engage tech support besides email.

Steinberg's website does not list Big Sur as a supported operating system for the UR 22c. I'll bet real money that's where your problem starts.

Big Sur is a major change in MacOS. I keep reading about musicians having problems with it because so many of the audio interaces don't have drivers for it. I have been holding off on installing big Sur until I know that everything I use on my Mac will work properly.

I suggest you consider running Catalina until the time a proper driver for the UR 22c is released.

I guess I'll wait for a email, My interface on Big Sur is working for Garageband and other applications of mine, but it wouldn't shock me if it was part of the problem. I have tried almost everything else. I hate to download Catalina another operating system.....
