I'm selling my iMac for a used MacBook Pro. The MacBook Pro I bought still hasn't arrived and I need to send off the iMac. The MacBook Pro is coming preloaded with some great software such as Final Cut Pro, reason, logic. So, I don't want the new computer to act like my old iMac but a there is some software and photos that I want to transfer obviously. What is the best way to do this? Migration Assitant or Time Machine? Or back up everything on external HD?
