macOS Sierra 10.12 - Shader is not supported on this GPU Error

Hello everyone,

I'm trying to create a sphere in which I play a VR video on Mac in unity and I found a shader script from the net which flips the normals of the sphere so the video can play inside-out.

Apparently, the shader doesn't work on my mac even though I have enabled the OpenGL renderer and removed Metal from the Player settings. Is there anything I am missing?

The shader works perfectly fine on my laptop which has Windows but I would like to work on my mac since it has better specs.

Thanks in advance.

 Shader "Custom/Flip Normals" {

    Properties {

        _MainTex ("Base (RGB)", 2D) = "white" {}

    }

    SubShader {



        Tags { "RenderType" = "Opaque" }



        Cull Off



        CGPROGRAM



        #pragma surface surf Lambert vertex:vert

        sampler2D _MainTex;



        struct Input {

            float2 uv_MainTex;

            float4 color : COLOR;

        };



        void vert(inout appdata_full v) {

            v.normal.xyz = v.normal * -1;

        }



        void surf (Input IN, inout SurfaceOutput o) {

             fixed3 result = tex2D(_MainTex, IN.uv_MainTex);

             o.Albedo = result.rgb;

             o.Alpha = 1;

        }



        ENDCG



    }



      Fallback "Diffuse"

 

Shader compiles fine on my Mac. Perhaps there's a missing closing brace? }
