- runjake 1y agoThis is the correct answer. And to add to it: macOS (and its derivatives, such as iOS) descends from an operating system called OPENSTEP (formerly NeXTSTEP), which used Display Postscript for on-screen rendering. Apple later replaced Display PostScript with a more modern reimplementation called Quartz 2D[1], which switched from Postscript to PDF. Why not PNG? Because PNG is a bitmap format and Quartz 2D is designed to be resolution-independent. Why not SVG? Probably because Quartz 2D relies heavily on the PDF specification throughout and it would be too much work to reimplement, and for what? PDF is still a common and well-regarded format. 1. https://en.wikipedia.org/wiki/Quartz_2D https://en.wikipedia.org/wiki/Quartz_2D
