That is concerning to hear. It's possible that the white paper was removed due to policy changes or other factors, but I'm not sure why it would have been removed from all the Mac devices.
However, the good news is that the original Bitcoin white paper is still available online through various sources, including the Bitcoin.org website where it was first published. It's important for people to have easy access to this foundational document that outlines the vision and technical specifications for the creation of Bitcoin.
If for whatever reason the white paper cannot be accessed through certain devices, there are still many other ways to obtain and read it. In any case, the ideas and principles behind Bitcoin are much bigger than any single document or individual, and they will continue to thrive and evolve well into the future.
