I have a new iMac and want to transfer information from an old iMac. The new iMac has no Firewire port. I have connected the two computers using the ethernet ports. The new iMac apparently cannot detect the old iMac; it is stuck on "Looking for Other Computers " I have just plugged in the new iMac for the first time and was attempting to be guided by the Setup Assistant, but quickly ran into this snag. Any suggestions? Thanks.
