iMessage is great when it works but it still needs a lot of improving. It works well on the phone but on the Mac it is far from perfect. A lot of the time it lags for me, fails to update the conversation. Messages need to be sent twice when sending after a long break.
Does anyone else have these problems? For me these occur every single time without failure.
I RARELY have any issues with iMessage on the mac. In fact, two folks sent me messages after I went to bed last night. They arrived on both my phone and my mac perfectly and were waiting for me when I woke up and turned on my mac.
