If I were to buy a MBP how do I get all of the info from my iMac onto the MBP? This is someone I would do on a regular basis.
I don't have a MBP but just want to see if it can be done before I take the plunge.
The OP needs to clarify if they are keeping the iMac and wanting to sync all files between it and the MBP while concurrently using both computers. OR is the OP simply replacing the iMac with a MBP and wants to move all the files over to the new computer. IT isn't clear in your OP.
It depends on how old the iMac is and what version of OSX it is running. Please let us know. The reason I ask is that I had an iMac which I could not use Migration Assistant due to not running a recent enough OS on it.
