How to set up IMessage on my mac:

hi,

Place the iPhone into Airplane mode for a few minutes.

When it is back in normal more Restart Messages on the Mac.

At this point the process should generate an alert type message from the iMessage Server on the Mac to says the iPhone is using the Apple ID and iPhone number.

Accepting the same places the iPhone Number in the Messages Menu > Preference > Account > iMessage pane > Received "alias" List.

It also places it in the Drop down at the Bottom as a potential "Send From" ID.

HI,

I once had an iPhone that was not showing it's own Number as ticked (Only greyed out).

Being greyed out it could not be change.

Although long winded I did the following:-

Took the Apple ID out of the Send and Receive part of Settings > Messages > Send and Receive on the iPhone.

Put the iPhone in Airplane Mode for few minutes.

On activating the iPhone I checked to see if the iPhone Number was re-ticked.

I re-added the Apple ID.

I put it back in to Airplane Mode for another few minutes (I wanted to be sure of a definite "Start Point")

When I had reactivated it I check both iPhone Number and Apple ID were ticked.

Then I restarted Messages on the Mac.

On the Messages restart I got the message from the iMessages server about what the iPhone was using and Accepting this placed the iPhone Number in Messages

Hi,

I have just noticed that your original Posts lists OS 10.8

and not OS X 10.8.2

Your phraseology in the last post made me look again.

Does you iMessage Account pane look like this ?

At OS X 10.8.2 Update the Messages App is updated to version 7.0.1

This changes the pic above (the Sign Out and Detail Buttons are no on the "Front" part)

The Send From Drop down has been added at the bottom. (You may only get this with Two active "Receive" names/iPhone Numbers)

It used to look like this

For the Points

I should have also said you need OS X 10.8.2 ( and the Messages Update) and iOS 6 to get the iPhone to Sync the Number as well as the Apple ID

All good now but frustrating! Thanks again, KK

I am going to try your procedure. I too got my number kicked out of iMessages on the Mac (called Messages).

From your iPhone:

After the Airplane Mode turns ON,

try turning OFF WiFi and BlueTooth,

give another 20 seconds, then turn Airplane Mode OFF,

give another 60 seconds before logging off iMessage from your Apple ID

wait a minute, then log in your Apple ID again.

(Apple's Message Server should be waken up by then).

Now, Sign Out from iMessages Preferences Accounts Apple ID

wait a minute, then re- Sign In with your Apple ID and check "Enable this account".

You shall see your iPhone mobile number as the first entry under "You can be reached for messages at:".

Does it work?

Had the issue, your solution did work for me! Thanks!

I had the same issue, your solution worked. Thank you
