Having made the jump from 10.7.5 to 10.9.3, bypassing 10.8 al together, it appears that I've missed a few features that are probably old news to some of you, so please bare with me. If I send a Message to someone from my MB Air, and they reply to that message, how do I get the message to go to my iPhone if the Air is shutdown so I don't miss the response. I'm not so concerned about sending iMesages from the iPhone because I'll always hear the "ding" and respond to it. If I don't open an iMessage on my phone, will it then appear, with Notification, on the Air? Thanks.
