So far it seems existing Roon servers that are upgraded to Sequoia are having the permissions issue. We’ll add more info to this thread as we learn more!
As a Macuser, I am as clueless as they come. But I know last week I upgraded one of my Macs to Sequoia. I believe it was my so far ignored almost completely MacBook Pro. For my BACCH gear I never allow any updates at all. Edgar says don’t look for solutions when no problems exist. He will mention to me if any updates are helpful or needed.
