Getting true pixel resolution from OpenGL on Retina displays

OpenGL OpenGL: Basic Coding
1

Hi folks,
My GL program is meant to run on any computer, but I’ve found that on OS X OpenGL displays my window not at the native Retina resolution but rather at point resolution i.e. Each texture pixel maps to a 2 x 2 square of Retina pixels.
Is there a way to ask OpenGL to give me the true Retina pixel resolution rather than the points resolution?
Thanks

See previous thread.

So there’s been no progress in 3 years?

Hasn’t anyone tried to swizzle prepareOpenGL to replace it and continue using regular GLUT?
