Frequent Crashing on MAC, Cannot Progress

[abowling]

I have a Late 2012 iMac
2.9Ghz Intel Core i5
16 GB Ram
NVIDIA GTX 660M 512MB

So far I love the game, but I have serious problems with random crashes. I've gotten as far as the Systems Control room (I think) where you are crawling through vents. Now I cannot get any further due to the game crashing. It will either crash as soon as the door opens, or as you walk around the room a little bit. The crashing 'episodes' have seemed random but quite frequent. I purchased the game today, and have spent roughly 4 hours trying different settings, updating the Cuda drivers, disabling running software, etc. without much luck.

Again, the game seems really great, and I can't wait to get further along!

One interesting note, when looking at the hpl.log, it gives multiple errors like this one:

ERROR: Couldn't create particle system 'ParticleSystem_16' of type 'D:/Work/studio/Frictional Games/Depth/redist/particles/smoke/fog_ambient_light_small.ps'

This is pointing to a windows directory, which wouldn't work on OSX. Possibly some files were not mapped correctly when ported to OSX?

I've attached logs, crash dump, and the system info from steam. Hopefully this will help out.

Thanks, and again -- awesome game!!!

I thought I should mention that I have the public_beta enabled, and it reports "Current content build 799088".
