secret Bitcoin document is hiding inside every modern Mac.

Any Mac computer that has been updated to use a version of the MacOS operating system since 2018 is hiding a copy of the “Bitcoin Whitepaper”, a technology blogger has found.

The Bitcoin Whitepaper was written in 2008, by a person or group of people calling themselves Satoshi Nakamoto and whose real identity has never been found. The document not only details how the cryptocurrency works, but also explains in detail the thinking behind why it was created in the first place.As a result, it has become an important document to those advocating for Bitcoin and cryptocurrencies in general.

That may be the reason that it was seemingly quietly added to the software, presumably by an engineer working on MacOS.

Inside the files for a device called “Virtual Scanner II”. The document appears to have been added as a sample file for that utility, and it may just have been a useful, short document to use as an example.
