How is OSX more unix-like than Linux?
- saagarjha 7y agoBecause macOS is literally certified BSD UNIX.
- iamaelephant 7y agoHow about in practical terms?
- saagarjha 7y agoIt’s POSIX-compliant short bugs which have unfortunately started cropping up more often as Apple reduces their focus in actually matching SUS.
- nineteen999 7y ago"BSD UNIX" bears little code in common with original Bell/AT&T "UNIX" due to the USL v. BSD lawsuit[1] anyway. The closest living relative of AT&T UNIX still in use at all is probably Solaris and it's successors.

- rodgerd 7y agoI'm not sure Solaris really counts as "living" any more. AIX seems healthier, notwithstanding the tradition distaste for it in a lot of the Unix world.
- nineteen999 7y agoBoth Solaris and AIX crawl on, particularly in the banking sector where there are decades old applications that still need a platform to run on. A bank I worked for 7-8 years ago had a project running to refresh the hardware platform for both for the next 10-15 years. IBM of course has the resources to prop up AIX as long as it has customers that depend on it, whereas Solaris is now pretty much dependent on the community. At least it is based off of SVR4 and not SVR3 (like AIX), has source code available, and runs on x86. Not sure that will be enough for it to survive into the future though.
- v64 7y agoIIRC, Linux has also deviated from the Single UNIX Specification/POSIX in some respects that would make it fail certification even if they tried.
