Be careful about file sharing. If you add a folder to network sharing, it requires permissions. What's better is to forget about sharing. Simply enable sharing in system preferences and stop there. If a user wants to get to files on Machine A, they browse to machine a in finder, pick connect as and log in as the user whose files they need. This way they can see everything. But if you spend time changing filesystem permissions to allow sharing of everything to everybody, you are going about this in a way which could lead to lingering file system permission problems.I work with several MACS- all interconnected. How to I give every machine permission to share everything with everybody?
