My wife and I have always used our own portables, we just purchased 27 inch iMac that we would like to share. Can I use migration assistant to transfer my data to the new iMac and then log off, sign in on her account on iMac and transfer her data onto her account? Will this method keep our iPhoto data separate? Is there a way to combine our iTunes easily? We were using home sharing previously. Any other tips would be appreciated in reference to transfer speeds (Ethernet vs Firewire) or any other important details. Thanks so much.
