T3D MIT Rendering Bugs

Hey all, I recently compiled Torque3D from the GitHub on my Mac, and have encountered some strange rendering errors and crashes. I was wondering if anybody knew of any fixes for the following:

The terrain renders with no texture (i.e. solid black). Geometry renders fine, it's just textures that don't seem to work. Example screenshot:

The player renders as a black shadow with no visible geometry except for some lights (decals?)

It seems to be a graphics driver or shader error of some sort. I'm getting these weird errors in the console as well:

I'm guessing this is just a graphics driver issue, as this runs fine on windows. All other parts of T3D seem to work as intended.

Thanks for any insight to my problems,
