Hello, my name is Dan.
You can use Migration Assistant to make the laptop mirror your iMac. This would take everything that's on your iMac and put it on your laptop just as though you were still at your iMac.
So that would be the same as targeting which is what my husband udoes. Where do I get Migration Assistant?
The Migration Assistant is located in Applications/Utilities. It does use the Target mode and then is connected via Firewire or USB cable.
You start the iMac in Target mode and use Migration assistant on the laptop.
That must be the same thing thanks I guess I didn't realize that it would move the mailboxes someties I become computer challenged ?
It will move everything that you tell it to.
