Using mac with High Sierra as NAS?

Hi - I used to be able to use my wifi connected macbook pro as a NAS. Since upgrading to High Sierra (10.13) and the new file system it doesn’t seem to work any more. The problem seems to be with file share type - neither options works - cifs times out almost immediately, nfs takes about a minute to time out. My guess is the new file system on the mac is invisible to volumio - will this be fixed any time soon? Or is it something else? Volumio version 2.296

Ahhh, crickets. Maybe I’m the only one. Redirect question - I can’t seem to delete the current non-working NAS connection - is there a secret trick for doing this? “Error: Cannot remove share”.
