How Do You Change Over-The-Air Settings On An iPhone 6S Plus
Trying to sync contacts between my iPhone 6S Plus ver.9.2.1 and iMac ver.10.10.5. OS X Yosemite, utilizing iTunes ver.12.3.2.35
In iTunes, I navigate down to INFO under SETTINGS for my iPhone 6S Plus.
In the body of the screen, just below the Apple icon there is an area that is titled SYNC CONTACTS. Within that area it states the following, "Your contacts are being synced with your iPhone over the air from iCloud. Over-the-air sync settings can be changed on your iPhone". I have explored the iPhone SETTINGS with a fine-tooth comb, looking for a menu that will allow changes to the settings for over-the-air syncing. I have not found any such settings.
For testing purposes, I have added new contacts in the iMac and the iPhone. I perform a sync, but neither of these trial contacts show up within the iMac or iPhone. At this point, syncing contacts seems to be hopeless!?
I trust that there is a Mac enthusiast out there that will respond and have a solution to my difficulty. In addition to solving this situation, I'd really appreciate a quick clarification on how iPhones and iMacs sync contacts. When SYNC is selected in iTunes while in INFO, are contacts synced in a bidirection method? Do iPhone added contacts get transferred to the iMac, and during the same sync do iMac added contacts get transferred to the iPhone? If not bidirectional, which device should I be entering new contacts on? I'm somewhat confused as to the direction of the sync (when it works).
Thank you in advance for your review of my question(s). I'm not new to Apple/Mac, but I still consider myself a rookie. This is my first post to the Apple Support Community, and I look forward to working with and being a part of the community.
