Thank you very much, has been very important to know that with Nvidia card, glChAoS.P (at least) runs on macOS.
Yes, Intel need of HD 4000 GPU, or above, that supports OpenGL 4.1.
Thanks to supporting me in macOS testing... No, I don't stop the OSX develop, but I need more collaborative people, like you (also tests and feedbacks, on several PC, are importants).
...and mostly ... I don't would your daughter to stop math study ... :D ;)
The Mac mini is still unhappy and says: ./glChAoSP_OSX Error: NSGL: Failed to find a suitable pixel format
But it's also an old Intel HD Graphics 3000. So please don't drop the macOS port it's working for most configurations.
