I'm feeling quite daft at the moment. I've tried the smb & cifs route to no avail.

I'm positive it's user error on my end. Here's my workflow:

I go into Mac finder and "connect to server", then I enter the smb/cifs route which seems to connect to the MC200.

Then I open "Roon" but it still doesn't seem to access the MC200 library.

(I recall that when I first installed Roon it automatically detected my iTunes library)

Is there some additional step in Roon that I must perform in order to access the MC200?
