There are not too many divers doing gas blending (this is fairly advanced stuff);
There are even less divers using a Mac...
I seem to be the only one who does it all (use a Mac, diving, gas blending and a little bit of coding).
This is really annoying because we (divers on a Mac) get no support for anything. One of the very cool features of some dive computers is that you can download dive profiles into a log book application. These app only with on M$ Windows (although some people are trying to make something happen on the linux side - see
www.linuxdiving.org).
There are 3 diving related apps that have been sorely missed by mac divers:
1. A log book app (with dive computer download capability)
2. A decompression app (I ported the CLI app MPlan so at least there is this)
3. A gas blending app (mine, I suppose, is better than nothing).
I had to buy VirtualPC almost exclusively because of the above. I guess I will have to try again...
