OK, here is my dilemma. I have a mac book pro that my iPhone syncs too. I have two iPads that sync to my Mac Pro. I want to have all my devices sync to the Mac Pro. What is the best way to get all my music (ratings, play lists, etc) and MERGE them with my macpro itunes. I have the same itunes store login on both machines, I also do not want to lose any apps, etc I do not have anything jail broken, but about half my music is ripped from my CDs and half is bought from Itunes. Everything I run is legit. Ideas?
