The OSX version was programmed by a college student who was interning and he quit a few years ago, as a result it has never been updated (ramp and random flow were later Windows updates), receive from unit never worked, it was a bug in the original OSX version. Storm mode is described in the PDF manual on the CD Rom, it is very brief and since it only occurs every few hours to days, it is not likely you will notice it but it should work. For now the only option to have all modes is to use it on Windows, however, once you update it for Windows, it will no longer work on OSX as OSX will not recognize the later firmware that must be installed.
We have a new programmer and he is working on an update, a new controller is in the works and will work on OSX, iOS, Android 3 and later and Windows 8 and Mobile, after this is released the goal is to go back and apply these platform updates to the 7096.
FWIW, I use Macs, so I advocate for updates for OSX, however, worldwide iOS and OSX are not the major players they are in the US, Android and Windows dominate, so it is not always easy to get people in a country where OSX is about 5% of computers and iOS is probably a quarter of mobile devices to see the importance. As someone who has reached out in the past to try to find a programmer or conversion solution, it starts at about $20K, so for the small global base, it is very hard to get priority. It will come, at least on the next controller generation, and since now all software is written in house by an employee, updates should be consistent for all platforms. They do hope to adapt the new software to the 7096, however the 7096 has some differences that prevent a simple install of the next gen software.
