Actually the button is there but it seems completely transparent, I can click on it and the slot it is connected to is called. The same implementation works like a charm on Windows and linux too.

Probably the problem is related to this statement in the QGLWidget documentation:

 On Mac OS X, when Qt is built with Cocoa support, a QGLWidget can't have any sibling widgets placed ontop of itself. This is due to limitations in the Cocoa API and is not supported by Apple.
