I've set up iMessage on my iPhone correctly (apple id) with Messages on my Mac (OSX Mountain Lion), and it syncs.
But the syncing isn't flawless.. Everytime I wake up my Mac after hibernation, it won't update my messages. I first have to restart the app a few times, to get all my messages. Sometimes even the order of the messages isn't correct.
From my experience the syncing is still quite buggy.
Does anyone have the same issues, and maybe a workaround?
ps: I don't use wifi on my Mac, if that's relevant.
