Please update to the hotfix (Roon version 2.71 1683) on the affected Mac and let us know if you’re still experiencing the problem.
Diagnostics indicate this machine is still running a long-outdated built, 1629. You might need to uninstall and reinstall Roon to force the most recent update. This won’t affect your Roon library or database.
We’ll watch for your reply. Thank you!
