In [[Apple Inc.|Apple]]'s [[macOS]] operating system, '''Quartz''' is the  [[Quartz 2D]] and [[Quartz Compositor]] part of the Core Graphics framework.  Quartz includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card. Because of this vertical nature, ''Quartz'' is often synonymous with ''Core Graphics''.<ref name="apple1">{{cite web | title=Apple - Developer - Graphics & Imaging Overview | url=https://developer.apple.com/graphicsimaging/overview.html | archive-url=https://web.archive.org/web/20041120084353/https://developer.apple.com/graphicsimaging/overview.html | url-status=dead | archive-date=November 20, 2004 | access-date=February 12, 2007}}</ref>

In a general sense, ''Quartz'' or ''Quartz technologies'' can refer to almost every part of the {{nowrap|macOS}} graphics model from the rendering layer down to the compositor including Core Image and Core Video.<ref>{{cite web | title=Apple - Developer - Graphics & Imaging Reference | url=https://developer.apple.com/reference/GraphicsImaging/idxQuartz-date.html | access-date=April 17, 2007 | url-status=dead | archive-url=https://web.archive.org/web/20111205191948/http://developer.apple.com/library/mac/navigation/topic_details/resourceType_10.html | archive-date=December 5, 2011 | df=mdy-all }}</ref> Other Apple graphics technologies that use the "Quartz" prefix include these:
