Thanks for the quick reply!  I am CC'ing Konrad on this email.  

How does one submit this bug report to Apple?  Do you have specific
details that you would want Konrad to send them?  Do you have plans on
submitting a report and would it help if both you and Konrad did so?

Technically, do you think that their OpenGL implementation does not
work correctly when the render mode is GL_FEEDBACK?  Afterall, the
shading works fine when the render mode is GL_RENDER.

If Konrad would like to submit the bug to Apple, I think your
suggestions on what to say will help.

Thanks again!

cheers,
