iPhone 6 won't sync all songs after iOS 8 update
This was in an iPhone 4s post but I'm seeing it with newer devices also so I reposted my comment.
Just got new iPad Air and iPhone 6 trying to sync with my MBP. Playlists won't all transfer properly. It deleted the contents of 2 playlists. Movies won't sync and when I select movies in the tab music becomes unselected and back and forth we go. I spent 5.5 hours (yes 5.5) at the Apple store with a very knowledgeable Genius. We tried everything.
Last night I successfully synced my iPad Mini and my iPhone 5s with the MBP, then restored to my new iPhone 6 and iPad Air. Over and over, only some songs came through and no movies or books. Today I tried again and with movies unchecked, most of my play lists synced, but could not get movies to transfer. Among all other attempts, we installed a clean copy of iTunes and also rebuilt all my preference files. In the store, we also added a "test" playlist with 1 song that transferred, when I got home I added my own and deleted "Test", but when I synced, "Test" was still there on the 6 and Air and my new list was not but still on the MBP. We did hard resets, diagnosis software, trial and error and all error. Just when it seems to work, it doesn't. I emphasize I had 5.5 hours of undivided attention from the best tech at the store. No fixes worked reliably.
I then synced my old nano and all the playlists came through fine. The tech and I are convinced that its a programming glitch between playlists and multimedia (movies.) Nothing else is affected on my MBP or other devices and it only affects syncing to the new units. Since I have all my other stuff, contacts etc and enough music, I guess I'll just wait till Apple gets it right and issues an update. My computer is fine and my devices couldn't both be defective. It was hanging on apps syncing but we manually told the iPad to download fresh copies.
At the Genius Bar, we tried everything possible. We had 4 Geniuses involved and can't solve it. I own or administer about 35 apple computers/devices and have worked on macs and repaired them for years (since my original Macintosh- that still runs). Never an issue like this.
This problem involves: MBP 2.4 Ghz i7- 10.9.5, 16g ram, 500GB SSD, NEW Iphone 6 64GB, NEW Ipad Air iOS 8.2 32GB
