@fclem, only happens on macOS since that doesn't use transform feedback.

This works. But I'm not sure what the preferred solution here, or if there is perhaps a more general issue here with using these types of shaders that might pop up in more places.

@nlate I just tried Blender 2.93 Alpha 321eef6a0c from April 3rd 2021 on an older MacBook Pro 13" with Intel HD 4000 running macOS 10.15.7 and there I can not reproduce the crash, this without a "Load Factory Settings" though...

For completeness sake I also tried with a "Load Factory Settings" and that also works without a crash.

I have exactly the same problem.
I Select the Cube (or any mesh) in the viewport and Add a Particle System.
I Change to Hair Type and Blender crashes immediately.

Blender versions (both) 2.92 & alpha 2.93

iMac (Retina 5K, 27-inch, Late 2015)
Latest OSX

Same problem here. I'm running 2.91.2 on a 2013 Mac Pro.

I'm going to try the latest version and see if it can be recreated.

Update: Yep, still an issue in the latest version.

Blender 2.93.5
MacOS 10.15.7

Hi this is still broken. I found a weird fix that works:

On default cube make new particle system.
Set emission to 0.
Now change it to Hair mode
Change Viewport Display from "Rendered" to "Path"
Change emission to any number
Render one frame
Change viewport display back Rendered. Done. You should be able to now add hair to any object without it crashing. You only need to do this once per session.

Thanks @calutron. Your trick also works around the crash on macOS 12.0.1 with Blender 3.0.0.
