It has been a while. My personal life got a little hectic (nothing bad) and I did not dive for almost a year but I am back in the water and so I am also back here.
As far as I am concerned the Mac Version (JTrak) is not very good, I now use a virtual machine (VMWare - Fusion) to run Windows on the mac so that I can use the Windows Version (Smart Trak) to get my dive data off the Galileo Computer. I continue to look for a good solution for IR dongle+Mac solution in the meantime.
Ultimately, I believe that there will be a solution to get the Galileo data onto the Mac-Dive application.
Here is a screenshot from inside Smart Trak showing the export options. Do you recognize any option that you may be able to use to import into Mac-Dive;

Best Regards
