OctaneRender® Beta 2.57 doesn't want to start on a 2010 Mac Pro.

I tried launching it from both 32 and 64-bit kernel starts. Crashes every time.

Mac Pro has:
two NVIDIA cards, Quadro 4000, GT 120
CUDA Driver 4.2.7
CUDA ToolKit 4.1

Mac OS X 10.6.8
24 GB RAM

The splash screen appears then OctaneRender crashes. Here is the dump:

Install CUDA driver and toolkit 4.0. 4.1 or 4.2 will not work.

Roeland

Thanks, I thought that might be the problem.

One question: how do I uninstall CUDA Toolkit 4.1?

Thanks!

Oh well, no help here. One thing I need no advice on is to uninstall OctaneRender.

Yeah well that's understandable if Otoy/Refractive don't provide support for their product.
The user community have probably grown a bit jaded about helping potential customers out of kindness after so long doing it gratis.
This ought to be a wake up call for the company but sadly it probably won't be.
The message that they need to get their business act together has been conveyed fairly bluntly to them on a few occasions now.
BTW I am not a Mac user so I can't answer your question, sorry.

First I would try running the cuda 4.0 installer and crossing your fingers that it will offer to uninstall the currently installed version of cuda like it does on linux.

I don't know how it works on Mac either, I would follow phen93's advice.

Ok according to the NVIDIA documentation (http://developer.download.nvidia.com/compute/DevZone/docs/html/C/doc/CUDA_Getting_Started_Mac.pdf)
You can uninstall your current version by
"...deleting the files from /usr/local/cuda and from /Developer/GPU
Computing, the default installation locations. (Note that older versions of the SDK
installed into /Developer/CUDA by default rather than /Developer/GPU
Computing.) Adjust accordingly if you placed the files in non-default directories. "

I think '/Developer/GPU Computing' applies only for the GPU Computing SDK which I assume you would not have installed so ignore that part.

Thanks for your advice. I did look through the NVIDIA documentation, but somehow missed that bit on uninstalling it. Thanks for everyone's help.
