I took some time this afternoon to update my hackintosh with the brand new OS X 10.10 codenamed Yosemite. Like the first time, I downloaded OS X Yosemite and put it on a bootable USB key (with Unibeast) following this tutorial about how to install OS X Yosemite on any supported Intel-based PC.
I installed OS X Yosemite with a Radeon HD 6870 (I tried first with a GeForce GTX 780 but impossible to start the installation with the GTX 780, no matter the command line options I entered at the Chimera boot screen: -x GraphicsEnabler=No, etc…). With OS X Yosemite and the ASUS P8Z77-V, only Radeon cards seem supported for the installation.

Once Yosemite is installed, you can change the graphics card: I started OS X 10.10 with the GeForce GTX 780 without problem. It’s cool, I can easily test my GPU tools with GeForce and Radeon cards on OSX!
Here are the “About this Mac” screenshots with the HD 6870 and the GTX 780:


With an OpenGL 3.2 context, 47 OpenGL extensions are exposed for a GTX 780 while only 43 are present for a HD 6870:


OSX 10.10 comes with NVIDIA R310.41 (a rather old driver…). But you can update the graphics driver with this one: R343.01. It works with Quadro and GeForce cards:

OS X Yosemite does not bring new version of OpenGL, we are still limited to OpenGL 4.1 like in Mavericks.
I quickly tested some GLSL Hacker demos and everything seems ok:


A simple PhysX 3 demo (PhysX SDK v3.3.2) — nope, there’s no GPU PhysX…
Flat buttons and flat icons remind me Windows 8/10. Flat world…


Next step: compilation of GLSL Hacker on OS X Yosemite with Xcode 6.1. I hope I won’t meet too many surprises…
So with 10.10 and new Nvidia driver subroutines bug (http://www.geeks3d.com/forums/index.php/topic,3730.0.html) is fixed?
I think it’s not better:

Wonder can it run Radeon R9 290(X) or not, last time I checked 290’s are not supported, but 280 are ( as 280 are basically a rebadged 7800 GPU )
