PLZ Support Cycles GPU Rendering Rhino for Mac cycle

I am using Rhino 7 for Mac.
I can’t see my Radeon Pro Vega 20 installed on my macbook pro.
So i can use only CPU Cycles rendering.
How can i use the Radeon Pro Vega 20 onRhino Mac?

You can’t as the Cycles devs dropped OpenCL support from Cycles on Apple platform.

A backend based on Metal is needed to bring back GPU support for Cycles on the Mac.

hi Nathan, do you have some news about the support for gpu on cycles mac?

Still non-existant. I haven’t had yet time to look into doing a Metal backend.

some news?

We are still working on getting primary dispaly features written and working in Metal for V8.
Any work on a Metal backend to support Cycles will take a back seat to primary functionality.
