So, I managed to find a different download link for FlexiStation for Mac, that had a "-i" suffix in the link. That is indeed an Intel binary and I can run it.
Unfortunately, this version (also 1.7) can connect and run, but crashes after a short time (variable, anywhere from 1-10mins). Hence, I'm still unable to use it.
Suggestions?
btw - I am a software engineer - I'd be happy to sign an NDA and get the source code and track down the problem myself!
Cheers,
