what you mean by simple raw?,
I mean at this point there is no simple one downloadable file option for public consumption. Raw recording on the MK3 has only been in existence for just over 2 weeks? I've been so busy testing I've lost track of time!

Lots of things aren't working well yet (like audio integration) and there's no guarantees that they will work. New test builds are coming out daily and a lot of them are broken. The post workflow is even more trouble and that's what I'm trying to focus on fixing now. The cinema5D steps work, just double or triple check you've filled every step correctly. Better to use a CF card, SD cards are too slow.
I'm on a mac too, it does work now.
if there's some confusion or issues with the cinema5D steps please contact Seb or Johnnie @ cinema5D, I'm sure you'll agree my time is better spent getting the raw post workflow working for everyone instead of user hand holding (that's not meant as an insult, that's what it's called in the I.T. industry).
I know your pain, I went through the same thing a couple of weeks ago. No pain no gain.
