this is a case of the missing data.
Bought my first Mac this week. Macbook Air with Lion. I launched iTunes and did an update.
My iTunes library is already on an external HDD that I used on my Windows PC. After plugging my external HDD directly into my MBAir, I pointed my MBAir's iTunes to my library on my HDD using the Preferences > Advanced > Change process. When my Music didn't show up after a reboot, I called Tech Support and they had me do the Library > Add to Library and hours later when that finished and because I had Copy Files to location checked, I ended up with a complete set of duplicates. At least I think that's why I got the duplicates. I've cleaned that up using some thrid party software but the problem I still have is that none of my playlists are showing up in iTunes.
I'm preparing to do my first sync to the MBAir with my iPhone and don't want to lose my playists which are still on my phone.
So here's the question. How do I get iTunes to see my playlists either in my library or from my iPhone when I sync? I know I need to check Transfer Purchases when I do the sync but I can't determine if that will transfer everything (playlists, ringtones, audiobooks, etc) off my iPhone or just purchased music.
