I'm a new guy here, I'm focusing the Mares ICON HD and still waiting for the air integrated version. Now I'm using a computer from another manufature, and I'm using a laptop with Mac system too, I tried to find a software again and again, at last I found one, it's not free, but it can be used for most of dive computers in several brands, I've got one and I've tried to use it with my computer, it's very nice. I didn't get the ICON HD yet, and the website of the software said the driver of ICON HD is not required, so I'm not sure if it will be worked with the ICON HD, but I think you can download the free version first and try it. This is not an advertising message, but I really love this software, especially the management of photos, it can work with the iPhoto to add the photos you took during the dive to your profiles, it's very interesting thing, but you should make sure your camera and your dive computer are in the same time system. Because I'm a new guy here, I can't post the URLs, so if anybody want to try it, you can try to search 'macdive' with google.
