Hi Matt, more thoughts:

   I will be interested in reading the conversation between you and Neil 
Houghton about resolving User ID 501/502 and permissions. I had problems with 
unmatched User IDs a few years ago.  Now I read Migration instructions - very 
carefully.

  Are you working within the “administrator” user account on all Macs?  Note 
the text mid-window below the indicator for "File Sharing: On" via Apple > 
System Preferences > Sharing.  There is an inference that Administrators can 
access everything, but other users can only access specific shared folders.

   I never use the Mac “Shared” folder for copying files between computers 
within my network.  I normally use “Share Screen” where I can navigate 
visually.  All user actions are at one Mac, either push or pull.  I usually 
drag files.  I can also drag files via the Finder sidebar (Locations) to the 
destination Mac.  I assume I could alternatively Copy then Paste which would 
make navigation more certain.  (I still don't have a clear idea of your method 
or wanted outcome.)

Cheers,
Alan
