As per gfx-rs/gfx#3716 (comment) :

macOS has a system shader cache at $(getconf DARWIN_USER_CACHE_DIR)/com.apple.metal

On my MacBookPro that is under /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C

• System shaders: /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/com.apple.metal
• Blender shaders: /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/org.blenderfoundation

Delete all the folders in there to clear the cache.

//  Fog helpers
//
//	multi_compile_fog Will compile fog variants.
//	UNITY_FOG_COORDS(texcoordindex) Declares the fog data interpolator.
//	UNITY_TRANSFER_FOG(outputStruct,clipspacePos) Outputs fog data from the vertex shader.
//	UNITY_APPLY_FOG(fogData,col) Applies fog to color "col". Automatically applies black fog when in forward-additive pass.
//	Can also use UNITY_APPLY_FOG_COLOR to supply your own fog color.

// In case someone by accident tries to compile fog code in one of the g-buffer or shadow passes:

// Quick try at doing a "print value" node for Unity ShaderGraph.
// Tested on Unity 2019.2.17 with ShaderGraph 6.9.2.
//
// Use with CustomFunction node, with two inputs:
// - Vector1 Value, the value to display,
// - Vector2 UV, the UVs of area to display at.
// And one output:
// - Vector4 Color, the color.
// Function name is DoDebug.
