Well compute shader is openGL4.3, and macOS is stuck at 4.1... for that reason it's removed from the releases:

openFrameworks/scripts/dev/create_package.sh

Lines 312 to 316 in c11edef

	if [ "$pkg_platform" == "osx" ]; then
	rm -Rf gles
	rm -Rf gl/computeShaderParticlesExample
	rm -Rf gl/computeShaderTextureExample
	fi

Do you mean a better error should be issued if openGL > 4.1 is requested on macOS? or should setupShaderFromFile() alarm if GL_COMPUTE_SHADER when #ifdef OF_TARGET_MAC?

what would be the ideal behaviour?

Yes, thanks for the reminder @artificiel.
Definetly it can be handled better, at least ofLogError but maybe std::exit with a message if the requested openGL version is higher than the system can provide.
