[osg-users] Does OSG work on Mac OS?

[Robert Osfield]

Hi (could sign with your name so we know how to appropriately address you
:-),

Apple decided to make developers life hard in their OpenGL support, while
it's easy to roll out support on other platforms on OSX, well... it's a
pain in the butt.  This doesn't just apply to OpenGL, Apple have done it
for their own API's as well.  OSX takes more work than Linux and WIndows
put together to support, alas only relatively small number of devs in the
OSG community to use/support it so it's greatest pain for smallest gain...

On the OSG side we have had to steadily implement a range of different
things to get things to work cleanly, lots of code has had to be rewritten
to properly support GL3 core profile under OSX, too many changes to make it
into the OSG-3.2.x and OSG-3.4.x stable releases.

In master we have the VertexArrayObject support built in and a number of
other changes that makes life easier under OSX, such using git master it's
now possible to develop under OSX with GL Core Profile.

Robert.
