Since I upgraded(?) to Catalina, I can’t access Nucleus and the attached hard drive in Finder, can’t add files to that drive, but Roon is finding the files and I can still play music from that drive.
Suggestions, or is this the same problem with permissions in Catalina?
From the finder, hit Command-K, in the pop-up box, enter nucleus.local (or its IP address), and the file browser window should open. From the KB: https://kb.roonlabs.com/ROCK:_Importing_Music
This is likely not the “permissions problem” in Catalina, you just need to re-add the share point.
