@glennseto@mastodon.social @evert@indieweb.social @rl_dane@polymaths.social @thomasareed@infosec.exchange Mac OS X initially used PDF for a lot of icons, because its imaging layer came from NeXTSTEP, which was based on PDF. (Which in turn was because Steve didn't want to pay royalties to Adobe for Display PostScript.)
For example, /System/Library/CoreServices/Dock.app/Contents/Resources used to have the PDFs for the dock's icons, like `poof.pdf` for the cloud animation when you dragged something out of the dock. There are still quite a few PDFs for UI elements under /System, but the number has been going down as successive redesigns have taken place.

@mathew@universeodon.com @glennseto@mastodon.social @evert@indieweb.social @thomasareed@infosec.exchange I had no idea! Well, I only used OSX from 10.5-13, so I probably missed some important bits.
