> So POSIX and the Unix Specification(TM) are standards No one fully supports POSIX. Aside from server systems like AIX or HP-UX Apple is literally the only company that has a POSIX-certified consumer OS (OS X since 10.5 Leopard [1]). > So my point, if anything, is that if Apple wants to maintain its credibility as a high-end computing systems provider, it needs to revert back to doing far more than paying lip-service to being a Unix vendor - and that includes bringing native support for X What's "high-end computing systems provider"? Apple is doing really fine as is. Why should they do "far more", and why does this "far more" specifically includes support for X? They supported X for years (OS X 10.2 to 10.7), and then decided it wasn't worth it (and it isn't).
