Roon setup on Mac OS trashed after my subscription expired; can't get it to work

[mjw (Here I am with a brain the size of a planet and they ask me to pick up a piece of paper. Call that job satisfaction? I don't.)]

On the MacBook try removing the application manually by following this post.

How to uninstall Roon completely..DB or something appears broken

The databases, settings, and artwork live in the /Users/USERNAME/Library/Roon folder. To get there: Open Finder and click Go in the top bar Hold down the Alt key to unhide the Library folder Click the Library folder Find and delete (or rename) the Roon folder Depending on how you configured Roon, there might also be a /Users/USERNAME/Music/Roon folder. Also, just drag the Roon or Roon Server application to the trash. If you delete those folders you should be all set! Cheers, Greg
