# Radeon ProRender on Mac: Object has no attribute cycles_visibility

I have downloaded Radeon ProRender 3.0.8 for MacOS. I am using MacOS 11.1 Big Sur with a AMD Radeon Pro 5300M 4 GB. This runs on Blender 2.91.0.

After installing the add-on I wanted to select the ProRender as the current render engine. However, when I do select ProRender, the viewport becomes empty and in the corner the following error message is displayed:

ERROR | Object object has no attribute cycles_visiblity. Please see logs for more details.


Under logs I have found the following:

Does this mean, that Radeon ProRender is not installed properly? Where exactly is the mistake and how to overcome it?

Why does my Radeon ProRender driver not work?

Note: I have found a post that says, that Radeon ProRender can be used for my device.

This post claims, that I have to switch off cycles. However, it is not even displayed as an option for me.
