Hi... The following post will possibly get me laughed off the forum, but I can't seem to find any way to do what I want to do. Hardware involved: PowerMac G5 (Leopard) Intel Dual Core iMac (Lion) MacBook Pro 15" (Lion) MacBook Pro 17" (Lion) Airport Express I want to use the G5 as a file server for the other machines in the house. It has a 2TB hard drive and I want to keep everyone's files (multiple users) in one place. I would like the process to be fairly transparent so the rest of the family don't have to do anything and all their files are saved automatically to the G5. Is this possible without a dedicated server? Thanks in advance for any guidance... I've been messing about with this for days and can set up sharing etc, but can't seem to get it to do it automatically for the other users.
