I am completely new to the world of shaders etc. so I am trying to be as specific as I can. I have an application where I use the a shader created by Unity see https://github.com/Unity-Technologies/TilingRandomization that randomises the tiling. In the Editor (I use it on windows) & when building it for Windows it works fine but on Mac something is wrong and I get these random reflections:
My suscipion is that it has to do with the metal part of the shader but I am completely out of my depth here. When I build the application I get the following warnings corroborating my suspicion:
Shader warning in 'Shader Graphs/TilingRandomizationTest_PBRLit_ShaderGraph': 'UnityMetaVertexPosition': implicit truncation of vector type at /Users/Alex/Documents/Work/researchProjects/OLM_project/experiment/unityProjects/Object-Location-Memory-Task/Library/PackageCache/com.unity.render-pipelines.universal@12.1.6/Editor/ShaderGraph/Includes/Varyings.hlsl(130) (on metal)

I am using URP with Unity 2021.3.1f1c1.
Edit: I played around with the shader and this problem even seem to occur if I disable the input on the metallic channel.
Edit: This doesn't seem to happen for every texture but it only happens on Mac.
