We have recently switched completely to Mac, I use a Mac Pro, the 3 kids and wife have iMacs, so total of 5 computers in the house. What would be the best way to network them together? I would like to make it easy to share files, music, pictures and the kids want to multi-play games together. We have a wireless network and wireless printer. I have for my work Mac Pro a backup hard drive (Time Machine) which is connected via USB. What would be the best set up to network them all together?
