When I look at the GIT repository you linked to I see that the last 
change was three days ago, which matches the last SVN commit. I would 
expect that all your changes are visible in both systems. But I did not 
see any Mac specific changes there.

If nothing shows up when painting, you may be missing a flush call. 
Maybe just add a glFlush() somewhere? In you code I see a call to 
flushBuffer, which may not be what you need (See 
http://renderingpipeline.com/2012/05/nsopenglcontext-flushbuffer-might-not-do-what-you-think/)

Hope this helps
