losing textures in mac build of game??

Unity Engine
1

Hello guys:)

I am preparing game for mac app store. while testing today, i noticed that I have lost ground textures in mac build. They work fine in PC build. Any ideas what would cause this?

Textures are .tga format.

I tried reimport and made sure all connections were good.

I also noticed, my radial blur is not working that I have attached to nitrous boost feature.

Thanks for any assistance…

test system is MacBook Pro with NVidia graphics card GT 330M
