Mac instability issues - video card vendor poll

[Master Tao]

I'm trying to narrow down causes for the OS X instability issues, so I'm creating some polls to test hypotheses as experimentally as is possible on the forums.

This poll is about the video card vendor as these issues may disproportionately affect one vendor over another.

So I have a Macbook Pro Retina 13"... according to my tech specs, I have an "Intel Iris 6100", so I chose "no discrete video card". Hope that's right..

[Master Tao]

That's right. Most Intel processors these days have include an integrated graphics processor, so even the Macs that have a AMD or Nvidia card also have an Intel processor.

What about my i7 iMac 27" with an ati 5750?

[Master Tao]

AMD. They stopped using the ATI name a few years ago.

I have a new MBP with Iris 6100 integrated graphics, runs fine and pretty stably, though about once every 3 hours (of total playtime) I get a crash to desktop with OSX's core dump saying "Graphics hardware encountered an error and was reset." However, this also has happened with other Unity-based games (Robocraft) so I'm just gonna chalk it up to Unity not playing nice with OSX Yosemite.

I'll keep an eye out for how stable it is when I can play (maybe tonight). My SSD is in, now I'm on 10.10.3 instead of Lion, too.

From what I've seen and experienced, 10.10 versus 10.9 makes a huge difference. Might want to bin based on that...

+1 for NVidia and more often than every 20 minutes.

Yosemite 10.10.3 + retina display + the following graphics info (I believe I'm always on the discrete nvidia when KSP is running):
