For some reason my iMessage app on my mac is not updating. It seems to have started after I installed the latest safari and iTunes updates from the app store. Not sure if they are connected though. I'm running Mavericks 10.9.4 Few things I've noticed. - Any message I send from the mac shows up on iMessage and my iPhone - Only certain messages I send from my phone show up on my mac Has this been happening to anyone else?
