Finally OSX supports 10 bit/colour (30 bit) colour.
HOWEVER, now the applications are lagging behind.
Capture One 8.3.4 uses the 10 bit colour option, but Photoshop CC does not.
Furthermore, only some displays make use of this option.
To check if your system/display supports 10 bit:
1) About this MAC
2) System report
3) click the Graphics/Displays tab
4) look for Pixel depth, ARGB8888 uses 8 bit, ARGB2101010 uses 10 bit
A good test file to check for 10 bit is:

If you see banding you are at 8 bit. if the gradient is smooth, it is 10 bit
