Can't sign in on iMessage and FaceTime after upgrading to ML

HI,

The different forms of your Apple ID will be regarded as Different IDs by the iMessages server.

The "Register" an ID you computer has to be able to supply the Serial Number of the Mac as part of the Security Process which ends with a Certificate for validation in the Keychain.

Open the Apple Icon Menu > About this Mac

Where the current Version of the OS is listed click the line twice (it changes to Build Number then Serial Number)

If it is missing you need to have it replaced.

It can be missing if the logic board has been repaired/Refurbished needing it's replacement

An Apple Store or Apple Authorised Service Provider should be the place to contact if it is missing.

My serial number starts with a W ends with a G - it has a serial number...

so i need my serial number for my imessages?

HI,

A "Certificate" to say the app has been Authenticated is placed in the Keychain as part of this Process.

As far as I can tell part of this involves the Serial Number once Messages gets to version 7.0.1 (with the OS X 10.8.2 update).

Open KeyChain Access in the Applications Utilities Folder.

See if you have an entry under the Passwords for iMessage (your Apple ID)-AuthToken

If you have then Double Click it to bring up the Info panel.

Check the Access Tab.

In here is it allowing Messages and IMAgent to access it ? (It may also list IMCore and InternetAccounts)

This could be set to allow Any app or have the "Confirm before allowing Access" option ticked.

If it is not there then open Console and try and login to the iMessages Server again and see if any messages about this turn up in the Console list.

HI,

From the other thread:-

Or using this far left "Face" icon will do the same.

I finally sorted this out by accessing the keychain, deleting any keychain entries referencing iMessage, restarted iMessage and my password was accepted and imesasge logged in.

I knew it had to be something local to my MBP as iMessage works fine on my iMac and iPad, after trying all the suggestions in this thread I finally took a chance based on Ralphs comment about the keychain... thank you!

Further to this, upon closing and restarting iMessage again, I am back to not being able to login...

HI,

In the Finder > Go Menu > Go to Folder type ~/Library/Keychains

Once in the keychain folder highlight the login keychain.

Then use CMD and I (Get Info)

In the Info Panel check at the Bottom that you are the Owner and have Read and Write Permissions.

Confirmed that I am and I do...

went through the process again of deleting all keys and killing imgent, restarted iMessages. It seems to allow registration, confirms that I can receive messages at my mobile number and @me @icloud addresses but when you go to send anything asks me to login and then fails.

I also have the same problem with Facetime.

Hi,

Both FaceTime and Messages with the iMessages account follow similar processes to Register even though it is at two different servers.

Both seem to involve the need to have the Serial Number listed on the computer.

I have read of someone who checked it against other details (sticker on Machine or the box if you still have it) and found it did not match.

I am not sure what else to suggest other than a Restore of the whole OS.

Just wanted to thank Ralph - deleting the keychain items for iMessage and Facetime solved my problem. Thanks!

You are welcome.

Turns out for me after following the advise of Ralph it did work until I restarted my macbook. I have now permanently fixed it by installing Lion over the top of my existing install, not a fresh install just a re-install... hey presto, Messages and Facetime work and stay working.

Cheers

The same for me,I have tried Everything. I have tried over and over everything listed and on each imessage, and facetime, even after installing Lion, it doesnt work. all I get it this after I log in for abou 2-4 seconds.

THIS ISSUE IS STILL THERE. CAN ANY ONE HELP US?
