Like on iOS, El Capitan’s Metal significantly reduces the overhead of graphics frameworks such as OpenGL by enabling low-level access to your Mac’s graphics subsystem. In addition to making El Capitan’s user interface and apps perform smoother than before, Metal for Mac is absolutely huge news for game developers and makers of graphics-intensive apps. When OS X 10.11 El Capitan launches this fall, it will feature Metal, a graphics framework Apple originally introduced for iPhones, iPads and iPods following the release of iOS 8 last fall.
