I'm having this problem too. I've managed to get a couple of things to render, but most of the time I get a grey or white render window. Using the free version from the Mac App Store. Mac OS Big Sur 11.2.3, MacBook Pro 2017 15", Radeon Pro 555 graphics.

@ davehetfield: if your Nvidia driver is up to date, probably you are missing the cuDNN library.
Please download and install 2020.2.1 Standalone.
You can find it by visiting your personal Downloads area:
https://render.otoy.com/account/download_archive.php
At first start, you will be asked to press the Download button, to automatically install a new cuDNN library to run it correctly:


@ DigitalOrigami: since you are using OctaneX, you have surely a different issue, probably related to not enough memory, AMD Radeon Pro 555 should have only 2GB of VRAM, so you cannot have too much geometry and textures in your scenes.
Please, open a scene that is giving you issues, then go to c4doctane Settings/Other tab, and, at the bottom of the panel, enable all the Log option checkboxes.
Then, load the scene in Live View, then in Picture Viewer, or until crash, then reopen c4d, navigate to c4doctane Settings/Other tab, press the Generate log report button, and share the octanelog_report.zip file, thanks.

Sorry, I'm not using C4D. I'm working with .OBJ and .FBX files. I'm sorry but I can't figure out how to generate a log file from the standalone version.
If you can see the images here, one shows an error I get when trying to open an existing file (.ORBX).
The other one shows me trying the metal material test (ie pick a metallic material and rendering it). As you can see, it errors out (the text in red below the viewport). 2 materials and 1 texture? There's got to be something wrong.

Hi DigitalOrigami,
in your screenshot, the scene seems to have a lot of primitives, but your GPU has only 2GB of VRAM.
Please open a new empty scene in OctaneX Standalone and try the Metallic material rendering again.
Please also make sure to have Mac Os 11.2.3 installed, to have the latest Apple Metal driver.

In general, 2GB of VRAM are not too much, and you can think to render only basic simple scenes.
You can go to the Kernel Settings and reduce the Parallel Samples to 1, to reduce the VRAM consumption at minimum, but you are also reducing a lot the rendering speed.
You can also enable the Out-of-core option in Octane preferences to move part of the scene from VRAM to system RAM, but you also lose another 20% or rendering power,

Since you should have Thunderbolt 3 on your Mac, better to think to add an eGPU via TB3, to use the internal GPU for system/monitor, and the external more powerful GPU for rendering only.
