So im awaiting delivery of my iMac 27 3.2ghz 8gb of ram 1tb FD GTX 680MX. It will be replacing a mid 2007 iMac. I want to transfer some data from this to the new one. only some, maybe like a couple documents from Pages,15 catalogs from lightroom4 and my iTunes. I dont want to transfer everything as I want to start fresh and dont want to bring all the clutter. Is Migration Assistant capable of this? if so how? I thought it just automatically transfers everything. i want to create new users and not migrate all the user data from the '07. What is the best way to do all this? And i bought the 16gb kit from Crucial. Can i just install this as soon as the iMac comes? Thanks for all your input! Cant wait for it to get here!!!
