Mac OSX, What Pragma's Don't Work?

    I have 2 shaders. One a fairly basic Surface shader. And the other, a frag shader in which the surface shader uses 'UsePass' on it. These shaders are working perfectly together on PC, but on Mac OSX it is just black. I really have no idea what the problem is. The surface shader is using "#pragma surface surf BlinnPhong #pragma target 3.0', and the frag shader is using "pragma multi_compile B AA1, #pragma fragmentoption ARB_precision_hint_fastest, #pragma vertex vert, #pragma fragment frag, #pragma target 3.0". Are any of these not compatible with OSX?

    This has been pretty frustrating and I would be very grateful if anyone could answer this question. :)

    I don't think any of those should prevent a shader from working on just Mac OS.

    Are you getting any runtime errors? Perhaps post the entire source?

    There are no errors or warnings on my pc. I haven't been able to get a hold of a mac with the Unity project open but have sent demo's to friends with macs and they all get black screens. Does multi-compile work with macs? Multi-compile has always caused me problems but its absolutely required for this shader. :S

    PS, I unfortunately can't share the whole source as this is part of a large project with a company.

    Nearly every shader that comes with Unity uses multi-compile. Multi-compile works fine on Mac OS.

    When you run the player on a Mac, it will produce a log that you can read with Console.app. Check the log for any errors.

    You also might want to ask your company to explain why keeping a Blinn Phong surface shader "secret" is more important than getting help making it compatible with a Mac.
