'Soma Quit Unexpectedly'

[Olk82]

Hello
Soma is not starting for me. It started initially and i played about 20 minutes, but now whenever I try and go in I get a Mac error:-

Soma quit unexpectedly.
Click Report to see more detailed information and send a report to Apple.

I can post some of the detailed report. I have tried entering the game through steam and through the desk top short cut.

All help appreciated. Apologies if this is covered elsewhere. Just want to play the game.
