It seems we may be getting some dinosaur hunting action on the Mac soon. Turok (remastered) was recently released on Steam for PC. While not 100% confirmed, a Q&A discussion posted on the game's Steam page states the following:
Q: Is it coming to Linux and Mac?
A: "Right now we are polishing the Windows version to the best it can be. Other platforms should follow soon."
It is entirely possible it is just coming to Linux and not OSX, but it does say "platforms" with a plural, so I imagine both Linux and Mac. We will just have to wait and see. I remember playing the Turok games on N64...man that was awhile ago. With any luck we can relive our childhood dino action in the near future.
