Thanks for providing the crash log. As Cameron said, I don't think that crash has anything to do with RWC. But it's puzzling - I just tried our final release on my Mac here and it loads up and works fine, nor did any crashes arise at all during our beta testing. Your log suggests the crash happened while MacOS was trying to allocate memory internally while compiling our shaders. However, it looks like you have 32GB of RAM and an 8GB video card, which should be plenty. It's possible it is some issue specific to your OS version or configuration, which would make it difficult for us to track down.
I did however look at all of the code that changed in the area that crashed for you, and made a few changes in it for our next minor update (expected soon). It's nothing that would explain a crash really, but sometimes the Mac video drivers can be very particular about things.
