System Information
Operating system: Darwin-17.7.0-x86_64-i386-64bit 64 Bits
Graphics card: NVIDIA GeForce GTX TITAN X OpenGL Engine NVIDIA Corporation 4.1 NVIDIA-10.33.0 387.10.10.10.40.135

Blender Version
Broken: version: 2.90.1, branch: master, commit date: 2020-09-23 06:43, hash: 3e85bb34d0
Worked: (newest version of Blender that worked as expected)

Short description of error
I can't use CUDA on Mac because an CUDA compilation error.

Exact steps for others to reproduce the error
When I trying to use GPU with CUDA I'm getting this error:

Are you using an official build or are you compiling Blender yourself? The current version shouldn't give you the option to select/use Nvidia GPUs for rendering. Nvidia stopped the development of new CUDA Toolkit versions for macOS. Consequently, Blender 2.90 does not support CUDA-based GPU rendering on macOS. This has been announced in the [release notes ]] and is also documented in [ https:*docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html#gpu-rendering | Blender's manual .

NVIDIA GPU rendering on macOS is no longer supported. Apple dropped support for CUDA drivers in macOS 10.14, and no recent Apple hardware uses NVIDIA graphics cards.

GPU rendering is only supported on Windows and Linux; macOS is currently not supported.

Until Cycles is ported to Metal/MoltenVK, GPU rendering will unfortunately not be possible.

Oh! That's the problem then... I did't know that.
Thanks for the info.
I'll use Linux for rendering then.

By the way, I'm using the official build and its giving me the option of CUDA...

@DanielCamino Unless I've missed something in the current Cycles development, that should not be allowed. Perhaps this is caused because you still have the nvcc on your system? I'll keep that ticket open and tag the relevant modules to take a look.

Sorry for my ignorance but ... what is nvcc?

Robert Guetzkow commented

2020-10-07 23:59:26 +02:00

It is the Nvidia CUDA compiler driver.

No idea if I have it, really.

I had the CUDA Toolkit installed. I have uninstalled it and it keeps offering me the CUDA option but it tells me I don't have any supported GPUs.
It is normal?

@DanielCamino Yes, that is what I would've expected.

As shown in your stack trace and previous screenshot, it seems Blender (erroneously?) still picks up the CUDA Toolkit when it is installed on macOS and attempts to compile the kernels for Cycles.

But in theory, if everything was installed correctly, should I see an OpticX option on my Mac?

Closing this old report since Cycles changed a lot with Blender 3.x and the recommended way for rendering on Mac is via Metal now. Please submit a new report if the issue still exists.
