My music collection is entirely on a 500 GB MyBook running through my current desktop PC. I am interested in a new Mac, but I am wondering, how will I be able to transfer all of my music files to the new Mac? Can the new iMacs read MyBook external hard drives? Do I have to burn all of my music files onto dvds? Must I get bootcamp and purchase Windows for the Mac? Please advise, and your assistance is most appreciated.
