I just downloaded the game and when I try to open it the introductory cut scene plays and then immediately takes me to a loading screen where it just freezes. The loading bar at the bottom of the screen is at 20% and just sits there.
I’m on a Mac with a NVIDIA GeForce GT 750M 2048 MB and 16GB of memory. I can’t seem to access any game options to play with settings because it won’t even let me beyond this initial loading screen.
Edit: I apparently was running Yosemite, which was a solid 3 years old. Upgraded to HighSierra and game is launching fine. Someone also said his/hers works with El Capitan as well.
