Well I just got my new iMac this morning, everything perfect! Anyway I have some songs that are in MP3 format. and some videos that I converted myself to an iPod supported format. Well when I sync all it syncs are just my iTunes purchased music. I tried just simply dragging and dropping them into iTunes but it will not work, so how do I put the other songs and videos into iTunes on my new Mac Also, I did authorize my new machine. New to OS X sorry if its a dumb question.
