Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Darwin-17.7.0-x86_64-i386-64bit 64 Bits
Graphics card: NVIDIA GeForce GTX 980 Ti OpenGL Engine NVIDIA Corporation 4.1 NVIDIA-10.33.0 387.10.10.10.40.137
Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-07-09 17:04, hash:
3623db7784Worked: (newest version of Blender that worked as expected)
Short description of error
I reported a similar problem (#78581) and my report was deleted because the video card was outdated (ATI Radeon HD5770 )
I upgraded the video card to an Nvidia GTX 980 Ti but get the same result.
Any attempt to view on screen with Cycles and a mesh in the model causes instant crash.
The replacement video card comes within the list of supported video cards.
It works fine in 2.83 and is recognised as a CUDA enabled GPU.
It is NOT recognised as a CUDA enabled GPU in 2.9, however.
Is the list of supported cards changing and out of date?
Exact steps for others to reproduce the error
Open a new document add a mesh attempt to switch the viewport shading to Cycles... crash every time
Thanks for looking at this... Chris

Changed status from 'Needs Triage' to: 'Needs User Info'
The NVIDIA GeForce GTX 980 Ti is a supported graphics card. Since you're still using macOS High Sierra (10.13.x) / Darwin-17.7.0 the driver is quite old, but I'm not aware of any changes that would stop it from being recognized on purpose, therefore this looks like a regression.(see comment by Brecht below)Assuming the Blender 2.90 is installed to
/Applications/Blender.app/Contents/MacOS/Blender, could you please open a terminal and run the following command to create a debug log in your home directory:/Applications/Blender.app/Contents/MacOS/Blender --debug --debug-gpu > ~/blender_debug_output.txt 2>&1Please try to make Blender crash again and attach the file to your bug report, as well as the crash log that macOS should create.

Not for CUDA rendering with Blender 2.90, that was dropped entirely.
@brecht Never mind, I was unaware that Blender dropped the CUDA support for all macOS versions in 2.90 due to Apple/Nvidia discontinuing the support for CUDA.
Changed status from 'Needs User Info' to: 'Archived'

The crash is still unexplained though.
@chrishartley While CUDA is no longer supported, could you please still run the command described in my first comment. This would help us identify the source of the crash.

As requested, I ran the debug script and have attached the bug report and the crash report.
I have to say I'm not thrilled to have just spent $600+ upgrading my video card only to be told you are now going to deprecate that, too!
The only need for the card was to be able to continue using blender past the 2.8x series.
You need to get this sort of info out there more quickly. The supported equipment list says that much older cards than mine are supported so I thought I was safe with this one.

@chrishartley The situation with GPU rendering on macOS is unfortunately a bit complicated. Apple has deprecated their OpenCL compiler. Additionally they stopped using Nvidia GPUs in their products, which likely contributed to Nvidia's decision that CUDA-Toolkit 10.2 would be the last toolkit version to support macOS. This was announced in November 2019. I understand your frustration and indeed this could have been communicated better in Blender's roadmap for the development on macOS. Please note that Nvidia GPUs are still officially supported for running Blender, this "only" affects GPU rendering with Cycles.
The two workarounds I can think of at the moment is either a custom build with CUDA support (not sure if that is still possible) or using Boot Camp to run Windows on your Mac.
@brecht This practically means no Cycles GPU rendering support for Blender 2.90 on any macOS version. Is there anything we can tell users other than to wait for Metal/Vulkan support? Can technically experienced users on macOS prior to 10.15 still build Blender with CUDA support?
@Blendify The GPU docs for 2.90 need to fixed , CUDA is still listed as supported on macOS.
Crash log looks like an issue with Embree and/or TBB.
So despite CUDA not being available for my GPU in 2.9 it SHOULD still run on my Mac?
The crash I get with Cycles and a mesh in a document is a bug?
As to Boot Camp and Windows... do I assume that this same GPU setup WOULD be supported if I run Blender that way?
Would Linux on the Mac be an option, too?
While inconvenient to reboot the machine between uses of Blender and my other software, if it allows me to stay up with the game while still using the power of my Mac's processors and memory it would be a useful interim measure. It seems that the only complete long term solution is to switch to a PC/Windows setup. In my case that comes with a heavy cost in terms of replacing my Mac software though.
...Chris
Yes, Blender should still run on macOS 10.13 and your hardware. The crash you're having will be investigated and hopefully fixed.
The NVIDIA GeForce GTX 980 Ti is supported for GPU rendering on Windows and Linux. Disclaimer: I currently don't have access to Apple hardware, therefore I can't tell with certainty if the GPU works well on Windows when using Boot Camp (especially if it's an eGPU?). There may still be some pitfalls with driver support that I'm not aware of.
Theoretically, yes. I haven't done this myself though and based on a cursory search this may require more tinkering than dual booting Windows. IMHO I would only recommend this for developers and people with tech experience.
When Blender gets Vulkan support in the future and thereby support for Apple's Metal API through MoltenVK (or even a native implementation for the Metal API), then it would be possible to have feature parity on macOS again.
I updated the docs in rBM6885.

@brecht @Stefan_Werner It seems that there are several people with similar issues on macOS:
I haven't merged them yet, because I can't verify if they have the same underlying cause (I don't have access to Apple hardware).
At first glance, looks like those are older Mac Pros crashing on illegal instructions inside Embree. Possibly Embree is detecting the CPU capabilities incorrectly? I don't have access to a Mac of that generation though. Maybe we need to run our own CPU detection and tell Embree explicitly what to use.

Sorry I'm not sure how this whole debug/revision system works but if I read this correctly there is a revision as yet untested on suitable hardware?
If so, am I able to test it for you on my Mac?
...Chris
Just to add, I have installed Blender 2.90 to my iMac (2014) with the same OS High Sierra 10.13.6 and everything runs fine.
It looks like that it is something related to the Mac Pro 2009 and 2010 that is causing the crash

@chrishartley
Yes, there is a patch in development that is not yet approved and thus not included in Blender.
If you know how to build Blender yourself and how to use git to apply the patch, then you can test this yourself. Otherwise, you'll just have to wait until other developers have tested it, the patch is possibly revised based on feedback and once it is approved it will be included in Blender.
Added subscriber: @EAW
@chrishartley in addition to building Blender, you would have to build the updated OIDN library to apply all of the patch I believe. Either that or build without OIDN. As it involves a library update, I would personally wait until it is merged, and then test it out.
OK, sounds like I should wait :-)
Just thought I might be able to help as this particular blend of hardware may not be too avaoilable for testing on.
...Chris
Here's a test build with a potential fix:

Can anyone test if it helps? I don't have the right hardware to test this.

Iv just tried on mc pro 5.1 os Mojave 10.14.6 amd WX5100 and render viewport and render still crashes on CPU.
My Blender still crash when set to render in Cycles
my system Mac 5.1
OS High Sierra 10.13.6
I'm afraid it is the same for me. Still crashes when I try to view or render in cycles.
MacPro 5,1 running OS 10.13.6 High Sierra on a SSD
2 x 6 core Intel Xeon processors running at 3.46GHz
96 Gb RAM
Nvidia GeForce GTX 980 Ti running three screens

Official release tested on Macbook pro mid 2012 os catalina 10.15.5. Working!!!
Just tried and still crashes as before.
Anyway, thank you for the dmg.

I managed to reproduce this in a virtual machine and found an alternative fix. The 2.91 macOS build on https://builder.blender.org/download/ has the fix, please let me know if it doesn't work.
Yupp.. Testing on my 2010 Mac Pro and now I can render happily. Both in viewport and Final 😃. Thank you..
Yes works on mine too.
Thank you! You guys are brilliant!
Pier
Me tooo!! Works. You changed my plans for weekend. My girlfriend will not like it. Thank you very much guys.

...and on mine!
Thanks for persevering, guys.
It is much appreciated
...Chris
I let you know that it works.
Thank you!

Hi there. Ok I got a little lost in reading all the above. So am I right that as of today, no fix or workaround has been found to use an Nvidia GPU in Blender 2.90/1/2. even if we are in High Sierra on any mac build at all and in the end a workaround was found for the CPU crashes but the GPU couldn't be. And no one has access to a version where it's possible to use? A read a guy mention a 2020 June build of 2.9 that still worked, but I can't find that version online anywhere. Advice is so welcome, Gerard
