Also the "log" doesn't look right. It's all pink and too bright. It has to be changed to represent something like the BMCC's log which is more accurate for color correction and appropriate for this kind of sensor.
Hey Guys, nice to see you here!
I don't have any color-cast issues on my Hackintosh at all (after setting WB, but I assume you did that).
Specs are i5 3570k, GTX570 TI, 16 GB RAM
Regarding the log curve contrast I have the following proposal:

or in Derive notation:
y = LOG((x + 2^(14 - z))/2^(14 - z), 2)*(1024/z)
"z" describes the amount of DR you want to map logarythmically into the picture. Don't know if that is a proper sentence, but I hope you know what I mean

Currently it's at 10, which brings 0 EV / 18 % grey in at 60 %. 7,8 should bring it to 50 % and 6,2 to 40.
From my PoV 8 stops of DR should be sufficient, since the Canon cameras are quite noisy in the shadows anyway.
If you would need more DR, the HDR curve is quite nice as well and, if exposure is adjusted, looks similar to Adobe Camera RAW's gamma.
You need to expand the highlights a bit, but that's a quick fix...
