Running Blender on Apple's MacBook or MacMini computers that have been installed with OS X "Leopard" have been facing a very serious setback in Blender's interface.
This problem is only confined to Leopard, so downgrading to Tiger is technically a solution. However (like certain other "new" operating systems) the newer computers are dependent on their installed systems, making downgrading next to impossible.
As the coders in the other thread said already:
There is nothing a blender coder can do to repair a broken OpenGL in the OS.
And disabling double buffering just because Apple released another bug is no option IMHO.
So what is this thread for ?
BM
Then we need a blender developer to tell this to Apple.
We? Do you have a mouse in your pocket?
The bottom line here is that Apple has shipped a version of their OS which has pitiful support for a commonly used OpenGL call when run on Apple systems with low end graphics.
See the bug tracker, lukep may have found a solution that doesn't involve disabling double buffering - apparently a opengl flag that was implicitly set previously now needs to be explicitly set.
