Blender's "stdio.h" not found anywhere

Question

Trying to run some OSL scripts for Blender 2.83 on mac. Never tried it before and having troubles with it.

Any script I try to run gives same error

ERROR: /Applications/Blender.app/Contents/Resources/2.83/scripts/addons/cycles/shader/stdcycles.h:31: error: error: could not find include file: stdosl.h
Error: OSL script compilation failed, see console for errors

Where "stdosl.h" is supposed to be? I can't find anywhere on my drive. Downloaded fresh build of Blender - no such file as well in any directories.

What am I doing wrong?

Answer 1

Figured it out. Downloaded Win version, copied missing file, works fine. Weird.
