Bolding
editThe bolding on this page is really distracting.--NapoliRoma (talk) 14:31, 15 July 2008 (UTC)
List Incomplete
editThis list is quite incomplete and for that reason, almost useless. Unless it is built into a reasonably complete presentation it defeats the purpose. What would you call it otherwise, "the Partial List of Unix Systems?" It is a misrepresentation otherwise. Stevenmitchell (talk) 02:50, 1 September 2013 (UTC)
- The problem can be partially rectified by changing the spelling to UNIX instead of Unix, in which case it would refer solely to systems qualified for UNIX trademark use. Of course, even then it's incomplete, and some entires listed would have to be removed. - Apotheon (talk) 19:50, 5 December 2013 (UTC)
- User:Apotheon, legally speaking, although the official case of the trademark is "UNIX", the title case "Unix" is still legally subject to the trademark–you can't get out of a trademark just by changing the case. I think this article should probably be called "List of Unix(-like) operating systems" (or something along those lines). There are multiple ways to structure such a list – (1) based on whether it is a major active system (something in active contemporary use for non-hobbyist/research reasons) vs not (historical systems, OS research projects, any notable hobby projects, etc); (2) based on licensing (open source vs proprietary); (3) based on trademark (systems legally authorised to use the UNIX trademark vs. those which are not). I think (1) is probably the most useful distinction to your average reader, followed by (2), and (3) is mainly of theoretical interest. SomethingForDeletion (talk) 04:37, 8 February 2023 (UTC)
- No need to fight. I already fixed the problem. Just add the registered UNIX operating systems. -GogoLion (talk) 23:20, 26 April 2024 (UTC)

macOS
editIsn't macOS Unix-based operating system? -GogoLion (talk) 06:44, 17 March 2024 (UTC)
- Yes and no. The answer is complicated by the fact you can call an OS "Unix" based on it being "genetic Unix", that is its code sharing the common origin with oficial Unix sources, or by being Unix certified, regardless of the origin of the OS itself. And macOS in a way is both! It traces its origin to BSD Unix which once was practically fused with official Unix. Then the Unix sources were removed from BSD source tree to make it free from Unix copyright and the result was a Unix-like OS sharing its origin with official Unix nevertheless. Then a BSD variant got adapted to become NeXTSTEP and then again it has been refreshed from FreeBSD codebase to become Darwin, which then again is the low-level base layer of the macOS. Then macOS got Unix certified, compliant to Single UNIX Specification Unix 03 standard. Then it officially became a Unix again.
