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

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.
