Tor thank you for your comment on locally-compiled Blender. I might try that one of these days!

Chad> Is this bug still present in 2.83 LTS using Big Sur 11.4? Im getting crashes in 2.93 that I don't get in 2.83, and that's with Bug Sur 11.3 (no way Im upgrading at this point...)

I'm now running Mac OS 11.4. And the news is still bad. The AMD graphics driver bug that was fixed in 11.3, and unfixed once again in 11.3.1, is still unfixed in 11.4. (So if you don't have other reasons to update your OS, use Blender a lot, and are still running 11.3, I'd suggest staying there. I wish I could downgrade, but one can no longer download the 11.3 installer from Apple as far as I know).

Apple automatically gets crash logs (probably many thousands per day of course). I think it's probably a waste of time for any of us except an official Blender developer to report this bug to Apple—someone who could likely point to exactly what the problem is. I for example couldn't really add anything to a report that isn't already clear from the crash logs.

I have had very frequent crashes with Blender 2.91/2.92 on an iMac 27" with AMD Radeon graphics card, running Big Sur, to the point that 2.92 was for me unusable. The crash appeara to be several levels down in the AMD graphics driver (com.apple.AMDRadeonX4000GLDriver)—usually a divide-by-zero exception. So I went back to using Blender 2.83.12, which did not trigger the crashes. And then I was delighted when Mac OS 11.3 came out a week ago, because the driver bug seemed to have been fixed, and Blender 2.92 worked fine again. However today (May 4) I downloaded and installed the Mac OS 11.3.1 update (which fixes a Mac OS security issue), and the same driver bug is back!! Blender 2.92 crashed immediately once again. So I suspect, as usual, that Apple's software quality control is at fault, and they rushed out this update without some of the recent bug fixes that were included in 11.3. With luck there will soon be an 11.3.2 update that pulls all the bug fixes together. Of course a Blender workaround must be possible, because 2.83.12 works. And also by the way I don't get these crashes with my laptop that's still running Mac OS Mojave, with either 2.92 or 2.83.12.

The following sentence appears on page Rendering » Shader Nodes » Introduction: "This method can us to for seeing painted textures while texture painting." (It's hard to understand what was intended)

(I'm not a real developer — just noticed this documentation bug and wanted to flag it)
