I recently upgraded to El Capitan with my current Monitor Display at 21.5", 1920 x 1080, AMD Radeon HD 6770M 512MB, 32 bit color.
I would like to know how calibrate my Monitor to Adobe RGB (1998) or ProPhoto RGB so that I can work in the same color space as Adobe Lightroom and my Nikon d750 camera.
I think you may find what you need in:

I followed the instructions on the OS X Daily link using expert mode and my screen turned dark. I deleted and started over thinking I did something wrong and it still looks dark. Is there video instruction available that I can follow?
Do you not see an Adobe RGB (1998) profile when you uncheck Show profiles for this display only..?
I do not know of a video, only > http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm
