Mac OS X 10.5 Leopard Receives Unix 3 Certification

Posted in IT at 8:36 by Borniet

Mac OSX is, as of version 10.5 (Leopard), no longer an Unix-based OS, but a true Unix version. On May 18, 2007, Mac OS X 10.5 received the UNIX 03 certification, meaning that Leopard conforms to the Single UNIX Specification Version 3 (SUS), which defines how components like the command shell, the compiler, and C APIs should function and behave.
This means that in the future, enterprise customers, who need ‘real’ unices to run their applications on, can also add Mac OS X 10.5 machines to their list with possible choices, as applications written for one Unix 3 platform are easily portable to others. This also means that developers can now easily start using Mac OS X 10.5 machines (like the iMac) to do their development.

The only other players in the Unix field that have Unix 3 certification are IBM (AIX), Sun (Solaris), and HP (HP-UX).

The certification, at this point, is only for the Intel-based version of Mac OS X 10.5

Welcome to the big world of major Unix players Apple!

(Probablly some sort of evolution joke there?) Like the FreeBSD Ports before it, it allowed System Admins and users to easily install Unix applications from the command line with a simple command or two. Macports brings that all to OSX and is an essential part of making it a true Unix operating system. […]
