Hello @noris
Here is a little update using Roon “All-in-one” version on my new Mac Mini M1.
It seems that the Roon UI aspect still hangs after a while.
I also noticed that the added bonus of running Roon on a M1 mac is that there seem to be some memory leaking involved here. The memory usage of the app keeps growing and I have to quit and restart the app after a week or so (if the UI doesn’t become unresponsive in the meantime).
