We will have a dedicated Mac solution in the very near future. Pelagic, our sister company and manufacturer of our instruments has a product in beta now. If you're interested, shoot me a PM; give me an idea of your interest level and background if applicable.
So what's the current status on this? Not being able to log our 4 Aeris computers since moving to Macs is maddening. I suppose I could buy Mac Dive or play with Subsurface, but that isn't going to help with transferring all our existing data from years in the Windows versions of ACI, nor are those programs going to help with dive computer functions such as setting the time, changing transmitter ID's, etc.
