Question: iTunes not syncing contacts with my iPhone 6+ and iMac
My contacts in iMac and iPhone 6+ used to syncing well through iTunes with cable. I only sync contacts with this way. Calendar is syncing with iCloud. It was perfect since day one when I got my iMac about two years ago. Just recently after one or two iPhone software update, I found something different, and the contacts are not syncing with each other now, even though the syncing process is just normal when I put on the cable, all the back up and process seems normal and no error appeared. The contacts syncing screen also show normal but actually they are not in sync. Have been to Apple Support for couple times and escalate to Apple Engineering but problem still not solved yet. Please help if you have any idea or experience this before. Cheers.
iPhone 6 Plus, iOS 11.2.6
