Not sure if it’s a Mac issue generally, or my machine specifically (8 core Mac Pro Late-2013, 64 gigs of ram, Dual FirePro D700 - almost as beefy as a Mac can be). Crashes running any level.
Gonna try Bootcamping later and seeing if it runs under Windows with the same hardware. If I’m feeling really ambitious, I may attempt to debug, but I have a feeling that until we get full Metal support, this may just simply not run on any Mac.
