Apple has hidden a copy of Bitcoin whitepaper on every Mac computer since Mojave in 2018, tech blogger Andy Baio has claimed. Written by Satoshi Nakamoto in 2008, the thesis titled 'Bitcoin: A Peer-to-Peer Electronic Cash System' explains how the cryptocurrency works. Baio said the file containing the whitepaper is named 'simpledoc.pdf' and he found it while fixing his printer.
