iMessage not working on mac

Try confirming your preferences on your macbook. Are you sure that yo are using the exact same email on both OS X and iOS?

Have you tried to re-setup messages? According to your error message, that might work.

Actually, though, I meant for you to confirm that the email of the recipient was the same.

HI,

Has this Mac been repaired or refurbished that involved a logic board replacement ?

This may mean the Serial Number was not "flashed" back to the board.

If the Serial Number is missing the Authorisation Token cannot be issued (And placed in the Keychain).

This seems to be new in Messages ver 7.0.1 which was updated with OS X 10.8.2

Ralph,

my machine recently repaired in Gautemala City, involved a logic board reoacement. Any advise on next steps? Is there any checks I can run to confirm the missing serial number? And if it is missing how do i go about getting it restored?

Regards,

Andrew

Hi,

There are two places you can look.

In the Apple Icon menu > About this Mac. This will display the OS version.

If you click this line twice it changes to the Serial Number

Also in the Apple Icon Menu hold down the ALT key when the menu is in the dropped position

The top item will change to the "System Information"

Launch this then look in Hardware.

Thaks for the prompt reply.

Serial number appears where you suggest.

Anything else I can try.

Hi,

It depends to some extent what message you are seeing in the app.

There is a sort of general "Messages cannot Register try Later" message.

There is a more specific "Messages cannot reach server" type message that was seen over the holidays, presumably as the server was too busy.

Adding Public DNS servers to System Preferences > Network > Advanced Button > DNS tab has helped some.

Some have found Stopping IMAgent in the Activity Monitor and then restarting Messages can help.

Sorry, I should have been clear from the start.

No error messages.

Worked fine prior to updating to Mountain Lion.

Can no longer login to iMessage - login option for iMessage app "greyed" out.

Have tried creating a new Apple ID.

Have tried public DNS.

Have tried keychain reset.

Have now tried stopping IMAgent also.

Best,

Andrew

HI Andrew,

Where are you seeing this "Greyed Out" version of whether iMessages in Logged in ?

Do you mean Messages Menu > Accounts ?

Do you mean Messages Menu > Preferences > Accounts > iMessages ?

If it is the second can you access the Account Details or Sign Out buttons ?

(I take it the "Enable this Account" box is ticked)

Ralph,

Messages Menu > "Log in" is greyed out.

Messages Menu > My Status > "At Home" is greyed out.

Messages Menu > Accounts > iMessage is ticked

Messages Menu > Preferences > Accounts > Apple Id: xxxxxxxxxxxxxxxx (shows active, Bonjour shows inactive) Enable this account is ticked.

Hi,

You found one place I don't use.

The Messages Menu > Login (Logout) of named account is about any Buddy list that is "Front".

For Instance Enable the Bonjour Account and go to Messages Menu > Preferences > General Section and Untick the line about gathering all Accounts in one list.

Now go to the Window Menu.

Your Bonjour account should appear in the list with it's own keystrokes (if you also have AIM or Jabber accounts they will be separate as well).

Highlight the Bonjour item to bring the Buddy List window to the "front"

Now go to Message Menu > Logout/Login and it will be dark and you can Log out of the Bonjour account.

If I use Messages Menu > Accounts to log out of all my Buddy Lists and leave just iMessages Logged in and even restart Messages the item reads "Log In CMD + L" but does not list the iMessages account.

Are you saying you can read the iMessages account here ?

Basically it refers to a front window (Buddy List) that you may not even have on Show.

If the iMessages account is the only "Account" logged in (No Buddy Lists) then the Messages Menu > Status items also do not apply and the iMessage account is either Logged in or not and has no Status.

At this stage I am not sure why the iMessage Account is not Logged in.

It is fair to say that there is no indication other than being able to Chat that it is ever logged in.

Ralph,

How do I give you the kudos points.
