>macOS is the most secure desktop OS by a long way, it's not even close.

GrapheneOS has become a desktop OS (because of all the work Google has done to adapt Android for desktop/laptop use) and its security exceeds macOS's.

You can connect a Pixel 8, 9, 10 or 11 to a USB-C DisplayPort-alt-mode hub and have a GrapheneOS desktop that way. In a few months, you might be able run GrapheneOS on a Googlebook.

Aside from that I agree with your comment, particularly your assertion that "Linux trails far behind" macOS in security.
