Specs:
Mobo - Asus P7P55D LE (BIOS V.2003)
CPU - i5 750
GPU - PNY Quadro 600

In win7 x64, Photoshop CS6 i have fully working 30 bit support, but in ML only 24bit, there is no 30bit mark

"30-bit Display (Windows only) Allows Photoshop to display 30-bit data directly to screen on video cards that support it"

Hi, it's possible enable 30bit colour mode if your hardware is suitable.
I've an Nvidia GTX770 GPU and a Dell U2711 monitor (DP), my SMBIOS is iMac14,2 and using SwitchResX (enabling billion colours) I've actived 30bit video mode.
I know Photoshop CC2015 don't support 30bit on Mac, only Windows (but Nvidia don't make driver for GTX boards only Quadro are supported) and the only software that work in 30bit are Preview and Photo so I've tried to open a B/W gradient ramp test image to verify if it works correctly but the image has banding artefacts so I'm afraid the problem is I need to change my SMBIOS to iMac 15,1 5K Retina the one for Apple has a monitor suitable for 30bit.
