Back when macOS was still called Mac OS X, (a subset of) PDF was the internal rendering format for Quartz rendering engine[0]. Their tech demo's also boasted about the ability to trivially edit PDF's. I don't know if any of that still remains in the current macOS versions, but I'm glad PDF editing and 'printing' (directory to PDF file or Preview as PDF) support was never dropped. Along with the excellent built-in screenshot and recording shortcuts. [0] https://arstechnica.com/gadgets/2000/05/mac-os-x-dp4/4/ https://arstechnica.com/gadgets/2000/05/mac-os-x-dp4/4/
