It can be found in macOS Catalina and later versions that Apple has hidden bitcoin white paper files in macOS.

CTOnews.com, April 6 (Xinhua)-- Andy Baio, a technology community blogger, recently posted a blog post on his Waxy blog, saying that he had found a file hidden in the macOS system. He says bitcoin white papers are hidden in macOS Catalina and later.

CTOnews.com learned from the report that he tested macOS Catalina and later and found this PDF file. However, it does not rule out the possibility that this file also exists in macOS Catalina and earlier versions. The user can open the terminal application and enter the following command:

Open / System/Library/Image\ Capture/Devices/VirtualScanner./Contents/Resources/simpledoc.pdf if you use Finder to find the file, navigate to the Macintosh HD-> System-> Library-> Image Capture-> Devices path, then right-click VirtualScanner.app and select "Show Package Contents". Next, do the Contents-> Resources folder-> simpledoc.pdf operation.

Another strange thing is that there is a file called cover.jpg in the Resources folder, which is used to test the photo media type, which is a 2634 × 3916 JPEG photo, which is a logo taken on Treasure Island in San Francisco Bay. There is no EXIF metadata in the file, but photographer Thomas Hawk identified it as the location of an almost identical photo he took in 2008.
