I just bought a new mac pro, and I'm currently using a firewire to transfer files from my G5 mac....or at least I think I am. I followed the on-screen instructions from the mac pro, and I'm at the point where it says tranferring files.....the screen has not changed in over 4 hours now....and there is no indicator showing me how far along it is...or if it's doing anything at all. Is this normal?
