I use Messages on mac to iMessage with contacts. Seems to be about 50% of the time I'll send a message and get the red exclamation mark, then click it and it sends. The other half of the time it sends just fine. It also seems to randomly be in sync with my phone, sometimes they are the same and at other times the mac will be like 15 messages behind and after I send a message it will catch up.
Does messages just suck this much or is there something that I might be able to do to fix it.
Note that iMessage on the iPhone/iPad seem to work just fine and stay in sync as I would expect.
