Didn't notice any syncing problem using iTunes 12.5 shipped with Mac OS X Sierra.Anyone else having iTunes syncing issues? I haven't been able to sync using b3/iTunes 12.4.2 and now the same with b4/12.4.3 on Windows. It finishes the backup portion then get stuck on the syncing portion when it gets to "preparing to coy items". The spinning icon on the phone goes away at this point and iTunes never finishes the sync. I'm wondering if I just clear my music library and start over if that would help but I don't want to not be able to sync all my music to my phone.
