How to Make iMessage work on MacBook?

Hi guys - I can't make my iMessage work on my MacBook Pro - It says that my iMessage account isn't registered AND that "The server found a wrong registration. Please try again later."

It keeps saying that so I don't know what to do. My iMessage works on my iPhone, so I know that my account works.


Any help? Please :-)

MacBook Pro, OS X Mountain Lion (10.8.1)

You mean Messages. Launch Messages. Preferences>Accounts. Is the Account enabled? From the menu: Messages>Accounts. Is iMessage checked?

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work.


Isolating an issue by using another user account


If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches. Try to add the account in the Safe Mode.

I've had this issue for a while on my 2012 rMBP and couldn't figure it out. I randomly decided to mess with it again today, and it worked when I did this:


Clear the Apple ID field. The Apple ID is automatically filled in for you, but I cleared the field and retyped my login email manually (and then the password of course).


For some reason, it works now. I'm not sure if clearing the ID field was actually the solution (I don't see why this would have fixed anything), but it's the only thing I did differently than all the previous times.
