Apple unlocks 'billions' more colors in latest iMacs
The latest retina iMacs already display colors very accurately, but with El Capitan, Apple now uses their full potential. According to German publication Mac & i, the new OS X version outputs 30-bits of color instead of 24-bits. That means that you can potentially see over a billion colors instead of 16 million on 2014 or 2015 5K iMacs, according to tests by Mac & i, though it may also work on other models. The feature only supports Apple's Preview and Photos for now, but may come to Final Cut Pro and other apps that can take advantage of it.
