Mac OS crash on startup

[jamesa333uk]

Hi - demo worked like a charm on my work Mac. Bought the game via Steam (I should have bought it via your website...) but having trouble getting it to work on my home laptop. I have also tried setting the max-texture-size=4096 option. Any help much appreciated!

Here is the log with the max-texture-size option:

nvm I just restarted my mac, and launched from the Lanunchpad rather than via Steam, and it's started to work just in time for Saturday
