I have a 2009 Mac freezes in 5 min. Running El Capitan 10.11.5. Tried everything, and I am frustrated. Love your game though. I was not really able to find proper nvidia drivers. Slightly confused on if there are any, but I did try downloading some; however, they would not install. Anyway, hoping you can help. I have tried reinstalling, but that did not work.
