This is to my best knowledge neither Stellarium's nor Qt's fault. At this
stage, glGetString is called.

from https://www.opengl.org/sdk/docs/man/ on glGetString:
=======
glGetString returns a pointer to a static string describing some aspect of
the current GL connection.
========

I understand these strings returning currently installed driver
capabilities. The version strings on my Windows/NVidia and Windows/AMD
systems always state something higher than 2.1, and these numbers
correspond to OpenGL version numbers detected by other tools. In various
bug reports concerning *nices, this also was always the crucial hint onto
pending problems.

Unless this behaviour is different on a Mac, this Mac may need a driver
update if graphic errors also show up (missing stars, planets not
rendered, ...). If all is fine in the graphics, the test has to be changed
or removed specifically for Macs to not show the warning.

If Mac GPU diagnostics show installed OpenGL 4 support for this card while
Stellarium reports 2.1, some action is indeed required, e.g. setting
default version requirements in QOpenGL... classes at startup. Optimally,
such a change should be incorporated in the pending change to Qt4.5
QOpenGL... classes, QGL... are deprecated.
