Alright, I see other people are having this problem, but none of their solutions seem to work for me. Here's the problem... I'm operating on a Mac OS X version 10.6.8 and an 8 GB iPod Touch 4. I upgraded to iTunes 11. I plugged in my iPod to update my music and no music was transferred. iTunes goes through the steps (ex. Preparing to sync...determining apps to sync), but when I check my iPod nothing has changed. I've tried the following: 1. Fiddled with manually managing music vs automatically -When on manually managing music, I've tried "Entire music library" and "Selected playlists, artists, albums, and genres" -I've tried only syncing Genius playlists 2. Using different iPod cords to connect with the computer 3. Changing my settings to sync over wi-fi (it should be noted that when I did this, the iPod did not register the change - so I guess none of my other settings are syncing either) 4. Changing the settings of adding movies/tv shows/apps/books/info (nothing was added/erased on my iPod) 5. Restoring my iPod to its factory settings (so now I have no music on my iPod) 6. Restarting my iPod and computer. 7. Authorizing and deauthorizing my computer I should also mention that I've tried syncing separately on all the different tabs (settings, music, and on this ipod). When I chose to manually manage my music and go to the "Music" tab, I check "Sync Music" (Selected playlists, artists, albums, and genres) and it says I have 500 songs chosen. Sometimes at the bottom, where it tells you how much free space if left (and what the other space is being used for) there is only a yellow section that says "Other" (right now it's telling me that I have 5.34 GB of free space). If I try syncing, it will briefly show the Apps and Music space that is being used, but then it always reverts back to just the yellow "Other" section. Lastly, after I try that and go back to the "Settings" tab, the "Manually manage music and videos" option is unchecked again. It all just seems really out of whack. I might be forgetting some of the things I've tried, but any other suggestions? I know I can still try re-installing iTunes (I'd probably go back to an older version) but I'd like for that to be a last case scenario.
