This works for me as well, however it does not last in regards to sending and receiving images. I usually need to go through this process once per day at this point.

I had these same issues, unable to sign in with my Apple ID to FaceTime and the new iMessage after Mountain Lion upgrade. Following these instructions to start in safe mode and then sign in again to Face time and iMessage solved my problem.

Both now working fine.

Okay i had the same problem and i called up apple and now it works perfectly for me 🙂

okay so follow these steps and it should work fine !

- Open your keychain access from utilities.

- Next step is that press on the keychain

- When keychain opens ----> press on Keychain Access which is next to the apple symbol (left top corner)

- Okay so after that press on keychain first aid in the drop down menu !

- Over there put in ur password and username and start the verfiy .

- If it says some error or verifcation not done ... then press repair and press start agian.

- Okay now after this it should work

but incase it doesnt work

(careful u may lose all ur keychain password so make sure that everything is saved somewhere)

- open keychain

- go to preferences

- reset my deafult keychain.

and all the things will go or else just delete all ur keychains and do that step

now restart ur laptop and ur imessage will work 🙂
