Green People

I must say this is very good, no lag (for me), but the strangest thing happend as i started playing: Everybody had red skin and green clothes! It only was on people. Everything else was Fine.
I looked this up online and it said that this would only happen with my type of computer ( Macbook pro 13inch 2.3Ghz Intel core i5 w/ 4gigs of ram and os x lion). It seems it Worked with snow leopard but not lion. I think the same thing happens to "starcraft" aswell.
SOMEBODY should make a patch for this? Apple or Ubisoft?
