ProRender doesn't work with Blender 2.79b for Mac. I have an eGPU and every time I convert materials and try to preview or render out all I get is an ERROR: Check log for details message. Does anyone know why this is happening?
I'm on a 2017 iMac with a Vega64 inside a razor X enclosure.
Why not try the Blender 2.80 version of RPR v2 beta instead? It does work a lot better on macOS and you don't have to convert as many nodes anymore (if any sometimes).
