iMessage will not sync with iPhone

Hi Eric,

Thank you for taking the time to respond to my inquiry. Unfortunately I still cannot sync between my iPhone 5 and iMessage on my MacBook. Any additional suggestions?

Here are the steps I followed in the 2nd link you provided: Messages – Fix Syncing Between Mac and IOS (2)

My notes are in (bold parens) below.

"First, you need to make sure all your devices are on the same Apple ID."

On each iOS device (iPhone, iPod Touch, iPad, iPad Mini):

1. Open Settings.app (DONE)
2. Go to "Messages" and make sure iMessage is On. (DONE)
3. If iMessage is on, "Send & Receive" will appear below it. Tap on it. (DONE)
4. Make note of the Apple ID at the top of the page. (DONE)
5. Select your phone number and email address(es) that you want to sync to that device. (DONE - See the 1st image below)

On each Mountain Lion Mac: (My note: I am on: OS X El Capitan Version 10.11.2)

1. Open Messages (DONE)
2. Click the "Accounts" tab in the top. (DONE)
3. Select your iMessage/Apple ID account, and make sure "Enable this account" is checked. (DONE - See the 2nd image below)
4. Select your phone number and any email address(es) that you would like synced. (My only option here is to select my Apple ID address)

The most important part is that everything is consistent across all the devices. (Image 1 below: under: Start New Conversations From - Should I select my Apple ID email address?)

Note that only new iMessages will sync - history will not.

If you are still having trouble getting new iMessages to sync across the devices try: (Still having trouble...)

1. Disabling then re-enabling iMessage on each device that isn't being synced to. (DONE)
2. Delete all your previous conversations: Some people have reported that they had to delete all of their conversations before things would sync up. (Don't want to do this - shouldn't have to)
3. Make sure you have your phone number added to your Apple ID account online. (DONE)

My note: In the screenshot of the iMessage "Send & Receive screen in settings on my iPhone, I have replaced my actual addresses and phone number with identifying information that is consistent with the content in each field.

I found a resolution to this issue:

MacBook > Launch Messages app > click on Messages in menu bar > Preferences > Accounts tab - when I followed this flow previously then clicked on my Apple ID Account in the Account list, there wouldn't be any dialog boxes to the right of the Accounts column. When I then clicked on the "Bonjuour" account also listed in the Account column, which presented the dialog boxes to the right, I then "re-clicked" on my Apple ID Account and now the dialog boxes appeared to the right. I logged in and was then able to tap on iPhone > Settings > Messages > Text Message Forwarding > enable > received a code to enter into the Text Message Forwarding field on my iPhone and was then able to successfully sync messages between my Apple devices.

Thanks again Eric for your reply.
