Not completely sure if it's compatible on Mac, even through Wine.
Although blue screens I believe have been associated with another problem before. I suggest just trying to troubleshoot it by restarting the client, running as admin if possible, etc.
If that doesn't work, perhaps delete everything that's in the MapData folder located in the game's directory if there's anything in it - sorry if I'm not much of a help, I've never used a Mac, always a PC.
Hopefully your issue will get solved somehow, I'll try to look into it as much as I can.
