iTunes fails to sync
You are SO not alone in this. Apple are a disgrace. Their 'updates' have rendered useful devices almost useless. I can now no longer sync calendar, photos, music or apps. iTunes just crashes at step 6 'copying'. Have reinstalled iTunes (ms7-64bt), have reset iphone5s (and lost a heap of stuff in process). iPad exactly the same but am keeping it well away from iTunes for now. Total b****dy shambles.
