Directional Light Shadow Render issue on Mac

I am transitioning from PSSM to Directional Light Shadow Renderer.

I am having issues on mac where any object with a material that has an AlphaDiscardThreshold does not receive a shadow. This issue is on Mac only, it is working on Windows.

I have uploaded a sample project to be tested with. Again this is only on mac.

Directional Light Shadow Renderer sample project

Could anyone please give me some guidance on this issue?

Thank you for your time.
