so i followed all of the steps in this support article from apple. now heres the twist that i need help with. i recently bought a new imac and i had a 1TB external hard drive from before. all of my music and movies are already on the drive but i didnt have it with me when i first was using my imac so i setup a itunes library on my imac. so when i hit consolidate in itunes none of the music and movies that i had from before are showing up in my itunes.
