In October 2015, Apple’s OS X El Capitan update enabled support for 10-bit colour output in certain configurations. At the time, this attracted attention because it offered photographers and image editors a wider range of displayed tones when working with compatible hardware and software.
The feature depended on the Mac, display connection, graphics hardware and application support. It was not simply a switch that would give every Mac and monitor a 10-bit workflow.
Petapixel published a useful walkthrough explaining how Adobe Photoshop CC users could enable the feature on supported systems:
