For the past few months Dorico has been loading with problems being flagged up in the Library Manager. I’ve put the samples on a different hard drive. I use Note Performer most of the time so I’ve shrugged it off - it’s just annoying.
I’m sure the message was real and if I’d wanted to use the files I would have run into problems. I applied the fix and everything now seems to be fine - I’ve loaded up a couple of instruments in Halion and they work. FWIW I’m interested at taking a look at Groove Agent.
I’d previous tried to reset the directories using the Library Manager but that approach didn’t work.
I posted it here as a fix just in case anyone else has the same issue.
Open your Mac’s System Preferences and select Security & Privacy. In the Privacy tab, choose Full Disk Access. Click the lock icon in the bottom left of the window and enter your macOS password. Ensure that Steinberg Library Manager appears in the list.
After that try again to move the files.
