As best I can tell from other sources, I have to consolidate the music on my PC (file---library-----organize library) before I can copy it to the new iMac, which will automatically create duplicates of every song on my PC??? And those have to be manually removed? You must be kidding. Can I not just copy the iTunes folder from one to another, since all my songs are in the iTunes folder? And I just noticed the new iMac has not been updated to the dreaded 11.1. Do the iTunes versions have to be same when you're transferring from one to another? I'd love to leave the old version on the iMac after unfortunately updating my PC version.
