I was not able to turn my MC200 Core off since I have no PC (only Mac) to run Core Control. As you note the only output was from my laptop. I did not care for the UI in my limited trial and asked them to cancel my subscription.

I can see where many here will use all of Roons features but that isn't they way I want to find and queue by music.
