Hello @Erik_Warn,

I’m so sorry to hear about the trouble :sweat: . And thanks for letting us know. We’d love to help :pray:

I was wondering, since this has been happening did you get a chance to completely reboot your Mac ( Core)? Could you please quit Roon, turn it off, unplug it for a few minutes, plug it back in, turn it on and launch Roon. Does that help at all?

If it doesn’t, could you please reinstall Roon? Please, make sure you have a backup first :nerd_face:
