Test failing on Mac OS X

When running the tests on my MacBook Pro I get an GL_INVALID_OPERATION error on generating a buffer. Seems like the Mac only creates an OpenGL 2.1.0 context. I found that GLFW needs additional hints on Mac. See http://www.glfw.org/faq.html#how-do-i-create-an-opengl-30-context

Adding the following lines after GLFW.Init() solved the problem for me.

@osx? begin
        GLFW.WindowHint(GLFW.CONTEXT_VERSION_MAJOR, 4)
        GLFW.WindowHint(GLFW.CONTEXT_VERSION_MINOR, 1)
        GLFW.WindowHint(GLFW.OPENGL_FORWARD_COMPAT, GL_TRUE)
        GLFW.WindowHint(GLFW.OPENGL_PROFILE, GLFW.OPENGL_CORE_PROFILE)
end : ()

I am still very new to Julia so there might be a better solution but maybe this helps somebody else.

I can confirm. I was getting the same GL_INVALID_OPERATION error on OSX. Adding this code to the tests/runtests.jl file just after the GLFW.Init() statement solved the problem for me too, and the test passed (visually too).

I have been having problems getting GLVisualize to work properly on OSX. The question is where should this fix be integrated in the package chain? In GLFW? In ModernGL?

Sorry about not answering, this is very low priority, since the tests
aren't really used. GLWindow should do this correctly, though!

Any error you have in GLVisualize should be unrelated to this. Can you open
an issue at GLVisualize?!
