Using a Mac, I am getting a Dx11 error. Why?

Hello, I am currently building a game on my mac, and I am getting a Dx11 Error message that “needs to be fixed” before I can start the game to test it. Why is this? Dx11 is only on windows, so I am really confused as to why I am getting these messages.

These are the messages:

Assets/PostApo/_origin/Standard Assets/Editor/Image Effects/CameraMotionBlurEditor.js(58,73): BCE0019: ‘Dx11Support’ is not a member of ‘CameraMotionBlur’.

Assets/PostApo/_origin/Standard Assets/Editor/Image Effects/DepthOfFieldScatterEditor.js(70,44): BCE0019: ‘Dx11Support’ is not a member of ‘DepthOfFieldScatter’.

Assets/PostApo/_origin/Standard Assets/Editor/Image Effects/NoiseAndGrainEditor.js(55,70): BCE0019: ‘Dx11Support’ is not a member of ‘NoiseAndGrain’.

If I could get some help, I’m sure my hair would appreciate it, since I have been ripping it out all night, lol.

Thanks in advance for your answers!

Dx11Support() is defined in PostEffectsBase.js. Does your project have that?
