This is what I am trying to do. I have an old iMac G4 (you know the white one with the dome bottom and adjustable screen) and I recently purchased a MacBook Pro. What I am trying to do is be able to access the same photos, music, emails, and calander on the seperate computers. Right now I have all my music and photos on an external hard drive and have it set up on my old computer to access it there. I have a wireless router for the laptop and was hoping that there is a way that I can access the same music and photos, plus have one computer recognize updates to email or calendar when made on the other computer. Someone please help.
