That’s because it doesn’t work with OS X currently. I’m building a port to OS X, if you’ll look just a few posts before yours, after which I will send it to and he can do whatever he needs necessary to verify it. One of the reasons it would be crashing is potentially due to deprecated flags by Autodesk, though I can’t be sure as I haven’t gotten there yet.
I’m still kind of new to the ART tools, so could you please let me know exactly WHERE it’s crashing, and what processes you’re doing, so I’ll know what to look out for when I’m testing on OS X? I’m running tests on 2014 and 2015.
