This will be disabling mipmapping.  Surely OSX GL3 core profile
supports mipmapping. this is a fundamental feature of texturing.
Perhaps the driver is broken.

Disabling mipmapping on text is not desirable as you'll end up with
aliasing artefacts when the text on screen size results in the texel
to pixel ratio less than one.

What happens you don't use the
font->setMinFilterHint(osg::Texture::LINEAR); hack?  A screenshot
would be useful.
