Octane Constant Crash

[skoeth]

I have the same hardware setup at home and had the same crashes too.
In my case the polygon amount was the problem. reducing it in the specific scene stopped the crashes.
Did you make sure to test that?

The overall "glitchiness" in the OS seems to be an driver issue on OSX, i have that on my iMac as well as on several MacPro Setups sometimes.
