Imessage Mountain Lion

Question

I've been researched to find the solution.
Since I installed the mountain lion, IMessage not working.
Already have activated and deactivated the email account in settings. Already deleted the messages on imac and ipad. and nothing.
Whenever I write a message it does not appear in the IMessage, and the person does not receive the message. If mandar ipad works well.
In these images is a conversation, and as you can see is empty and did not receive the messages. Nor can receive messages on Imac.
I also did reset PVram and neither worked.
conclusion:
Ipad works well
Imac does not receive, not send, and will not appear messages.
Ps - I used the google translator sorry for the bad english

Answer 1

Your phone number is not associated with your Messages account. You must set that up, first. Although the Preferences say Add Email, you can add a phone number. It must be in the International mobile phone number format (ie + country code, phone number).
Setting it up from the preferences may not require you to delete the converstations from your phone.
Also note that Messages will not send to non-iPhones nor will it sync messages from your iPhone that are to non-iPhone users.
