Mac User Issues With OpenAura/ Fixed with Garry's Mod 13?

Alright I have been having issues with getting on HalfLife2 RP servers that use OpenAura. When I get on, the screen is rather dark. I have looked into it and it appears not to be me but every Mac user. My question is do we know if this will be fixed when Garry’s Mod 13? I know there is a small percentage having this issue, but it would be nice not to limit what servers Mac users can be use. I have emailed G-mod support, tweeted Garry and now I am posting on here. Or is there also a fix I haven’t found yet for this issue? I hope there is a easy fix for this. I keep finding awesome servers to play on but are unable because if this problem. Can anyone help me out?
