Installed Sapphire RadeonHD 7950 Mac Edition in MacPro 5,1 2010 running El Capitan.
If you need to purchase Mac OS X 10.7 Lion, you may order it from this page. The most current version of OS X is OS X 10.9 Mavericks. To learn more, please click here. What do you receive: An email with a content code for the Mac App Store. Note: Content codes are usually delivered within 1 business day but may occasionally take longer. OS X Mountain Lion (version 10.8) is the ninth major release of OS X (previously Mac OS X, now called macOS), Apple Inc.' S desktop and server operating system for Macintosh computers. OS X Mountain Lion was released on July 25, 2012 for purchase and download through Apple's Mac App Store, as part of a switch to releasing OS X versions online and every year, rather than every two years or so. I have a Sapphire Radeon RX 480 8GB Reference card and my Mac does not recognize it. I have found several guides that told me that I could find AMDRadeonX4100.kext in the Extensions folder, however I could neither find said kext or find an online download link. Currently, in 'About This Mac' under graphics it says 'Display 8MB'.

Mac OS X 10.11, also known as 'El Capitan' is certified with Sapphire 8 or higher only. It is not compatible with any version of Sapphire prior to Sapphire 8.
There is a drivers disk enclosed, but of course it would be dated by now, since it's no longer produced.
Does the card require newer driver updates for El Capitan?
Card boots and appears to run fine, although PhotoShop CC 2015 states 'Photoshop has encountered a problem with the display driver, and has temporarily disabled enhancement which use the graphics hardwire... check the manufacturers' website for the latest software'. Checking Photoshop's prefs, it has Performance / Use Graphics Processor checked OFF (which is where the Graphics Processor to Accelerate Computation and OpenCL settings are)
I see threads from 2014 about OpenCL compatibility with the 7950, but those are dated and reference Lion and Mavericks.
