Thanks for the link :) I have already setup a samba share (actually I have setup all 3 on my server xD).
Nice :) With Samba you can also create guest entries without passwords for visitors while having your private files behind your own login. Here an example of guest access : std.rocks/gnulinux_samba_no_password.html
And apart from that Samba should be fine for access from MacOS and Windows clients unlike with the ancient NFS, which I expect to be more troublesome to connect especially on Windows, though that is a wild guess.
