Maybe it was written as a parody and we just don't get the joke? (Not POSIX, the article. POSIX survives fine outside of UNIX in embedded systems and somewhat on Mac OS and Windows.)

macOS at least is definitely posix compliant - not just somewhat. It was a big part of what was needed for xserves to be competitive (alas being shiny and aluminium was not :) ). While xserves have died, macOS remains entirely posix compliant - complete with the horrific %n format specifier (although an environment variable is needed for it to be respected in non read only format strings iirc)

  %n isn't from POSIX. It has always been taken from the ANSI draft.

  It's arguable that macOS is actually POSIX compliant. I was frustrated that poll() simply refused to work on terminal devices in Mac OS X 10.1 and I had to use select() instead. And it's still not supported in macOS 13! Can you claim POSIX compliance while actually not complying, by saying "BUG: currently doesn't comply" for more than 20 years? https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/poll.2.html https://developer.apple.com/library/archive/documentation/Sy... > BUGS > The poll() system call currently does not support devices. https://pubs.opengroup.org/onlinepubs/9699919799/functions/poll.html https://pubs.opengroup.org/onlinepubs/9699919799/functions/p... > The poll() function shall support regular files, terminal and pseudo-terminal devices, FIFOs, pipes, sockets and STREAMS-based files.

  There are no environment variables to disable this behavior.
