I've recently updated my Mac to High Sierra and since then I can't use Finder with my Raspberry Pi's. SSH and VNC work but Finder comes up with "There was a problem connecting to the Server ...".
The Pi's are visible and the network seems to be OK. (I can SCP files between the Pi's on the network).
Any thoughts? (Netatalk on the Pi's is at the latest level and I've got a mixture of Jessie and Stretch and they all exhibit the same answer).
The problem went away. I'm not sure why but it is obviously something to do with my network. If I enable WiFi on my Mac, everything works fine whether the Pis are connected WiFi or Wired. If the WiFi is not enabled, then Finder gives the error. I'm not planning to investigate further.
