The app OpenGL Extensions Viewer crashes on 10.8.4 when running any of the tests on the core profile. I have an iMac7,1 with an ATI gpu. The app has actually been crashing since 10.8.3, and I've tried to contact the developers about it without success. Is anyone experiencing/ can confirm this? I'm wondering if it's an issue with my app install specifically. OpenGL Extensions Viewer is a free app available on the app store and is widely regarded the standard from looking up what OpenGL extensions are available on your mac.
