Nice work! I'm very keen to see if this fixes some issues we have with
OSX. Specifically, if you remove the ifdef from
https://github.com/qgis/QGIS/blob/master/src/gui/qgscolorbutton.cpp#L505

Does the color picker work?

And if you remove
https://github.com/qgis/QGIS/blob/master/src/app/qgisapp.cpp#L2007

Do preview modes work?
