Hi,

I noticed that my macOS instanciate a GL4bcImpl (which seam to indicate that the device supports GL4), but that the version indicated by GL.getContext().getGLVersion() returns "2.1".

I am surprised by the second one - which is however consistent with string provided by GLXINFO :

OpenGL version string: 2.1 Metal - 71.6.4

All my macOS, even the youngest one return this 2.1 string - which would be surprising for Apple since OpenGL 4 has been released several years ago already (and is now deprecated).

Is there a different field that I should check to verify the max OpenGL supported version on macos?


System.out.println(drawable.getGL().getClass());
System.out.println(drawable.getGL().getContext().getGLVersion());
