UPDATE 24/10/2019:
build 41.16 fixed the issue. Thanks Devs, now the game is totally playable on macOS
Hi there! I'm trying to play Build 41 on a MacBook pro early 2015, OSX 10.13, 16GB RAM, i5 3.1GHz CPU. I disabled all the mods I installed for build 40, and started a new game. Things are fine at the spawn point, but as some zombies show up on the screen the game starts to freeze for about 10 seconds. This happens 2 to 3 times until the game finally crashes to the desktop. I tried 3 times and it always happened with zombies on screen, the starting house is fine. Any clue?
