In Mac OS X v10.5 Quartz 2D Extreme was renamed to QuartzGL. The Quartz Compositor is the compositing engine used by macOS. In Mac OS X Jaguar and later, the Quartz Compositor can use the graphics accelerator (GPU) to vastly improve composition performance. This technology is known as Quartz Extreme and is enabled automatically on systems with ...
macOS Sonoma supports Macs with Apple silicon and Intel's Xeon-W and 8th-generation Coffee Lake/Amber Lake chips or later, [25] and drops support for various models released in 2017, officially marking the end of support for Macs without Retina display and the 12-inch MacBook. The 2019 iMac is the only Sonoma-supported Intel Mac that lacks a T2 ...
The bitmap output from Quartz 2D, OpenGL, Core Image, QuickTime, or other process is written to a specific memory location, or backing store.The Compositor then reads the data from the backing stores and assembles each into one image for the display, writing that image to the frame buffer memory of the graphics card.
This feature is called HighDPI mode in macOS and it uses a fixed scaling factor of 2 to increase the size of the user interface for high-DPI screens. Apple also introduced support for scaling the UI by rendering the user interface on higher or smaller resolution that the laptop's built-in native resolution and scaling the output to the laptop ...
The earliest widespread implementations using this technique were released for the Mac in Mac OS X 10.2, and for Linux in a Luminocity prototype. Currently, window managers using OpenGL include Compiz, KWin, and the Quartz Compositor, while Desktop Window Manager currently uses DirectX 9.
With the release of Mac OS X 10.2, marketing attention focused on Quartz Extreme, the composition layer, leaving the term "Quartz" to refer to the Core Graphics framework or just its 2D renderer. Presently, Quartz technologies can describe all of the rendering and compositing technologies introduced by macOS (including Core Image for example).
