iPhone 6s not syncing.
since a battery replacement my 6s refuses to sync contacts with my Mac Pro laptop. I have tried all the usual methods of resetting, restoring etc but with no success.
I am now having duplicate contacts on the Mac Pro😮, is this issue linked with iPhone 6s or a completely separate problem.
any thoughts other than the hammer would be great.
both devices are running current operating systems and have the correct time.
