Andy Baio has made quite a find:
While trying to fix my printer today, I discovered that a PDF copy of Satoshi Nakamoto’s Bitcoin whitepaper apparently shipped with every copy of macOS since Mojave in 2018.
I’ve asked over a dozen Mac-using friends to confirm, and it was there for every one of them. The file is found in every version of macOS from Mojave (10.14.0) to the current version (Ventura), but isn’t in High Sierra (10.13) or earlier.
My guess is that this is probably sample media for a driver for some scanners or multi-function peripherals, but it is sure weird. (Now that Andy has made us all aware of this, I assume this PDF will vanish in a future software update.)
