Metal

Iron, copper, mercury, (all three are metals) shaders (it’s a low-level 3D graphics, shader and compute API for Apple silicon GPUs).

2: Silica successor to 3 went from 2D to extreme.

Quartz

Silica (the mineral quartz) successor to 3 (it progressively replaced QuickDraw in Mac OS X) went from 2D (Quartz 2D) to extreme (Quartz Extreme, with hardware acceleration).

3: Classic climbing extender replaced by 2 and all but vanished now.

QuickDraw

Classic (it was the graphics library and API in Classic Mac OS, and initially written by Bill Atkinson and Andy Hertzfeld) climbing extender (a quickdraw) replaced by 2 and all but vanished now (in Mac OS X, Quartz 2D has replaced it, with barely a trace left in modern macOS).

They have each been key parts of the Mac’s graphics system.

I look forward to your putting alternative cases.
