Apropos OpenGL and shaders: Is it possible to get GLSL version 130 version on mac? If not, how do I get a newer version?

(I can’t get Ruckus to run mac)

To see which versions of GLSL that were supported I tried different values for the version in: https://github.com/cbiffle/ruckus/blob/master/viz/preamble.glsl

Version 120 seems to exist - but the preamble uses more recent features.
