Problem playing this on a Mac

[Aryn Whistler]

Hey guys, I'm having problems with shading and textures on my Mac, and I've seen a bunch of other people asking for help with this, and none of the solutions have worked for me. I've turned plant shading to full, I've turned off grass, I've downloaded the shading patch for Mac on the moddb page and replaced the files, I've dowloaded the mod online and on steam, I've turned off HDR, I've event deleted font_data.xml in Data which someone said to do. Despite trying all these things, the map still looks like a weird milky white color, and in battles, the ground is white, and the trees are a bunch of white polygons. Can any of you guys help me out here.
