Transfer data from one mac to another

The easiest way will be target disk mode, hold cmd-t while starting the macbook while it is hooked up to the imac and it becomes an instant external harddrive

 

well, that requires you having a firewire cable lying around.

If you have a network, you can transfer the files across the network. Just make sure sharing is turned on in system prefs, then you should be able to see one mac from the other and copy the files across. You might also want to look into some software (fox example, Chronosync) that will keep the files on each machine in sync with each other)

 

Best way is to use the Migration Assistant. We use it at work when doing upgrades. Easiest way is during setup, or afterwards as long as the name is different on the new computer. Otherwise it'll ask to overwrite your new account. If that's too much of an issue, I recommend the Target Disk Mode anyway. It's easier IMO than going across the network. There's nothing to setup, the old computer will just show up as an external hard drive. If you already have a network, and they're both able to connect to it via your router, then you can enable sharing in the system preferences if it isn't already. Then just connect via the Finder.
