I've just for the first time signed into iMessage on my Mac, having only previously used it on iPhone. I'm just trying to get my head round it so I don't start missing messages - for example, if I'm away from my desk and I get a message, it alerts me on my Mac, but will it also alert me on my iPhone? At times I leave my desk for 30 mins/an hour and don't want to get back to my desk to find I had a load of messages but they didn't notify my iPhone!
