Leopard is now an Open Brand UNIX 03 Registered Product, conforming to the SUSv3 and POSIX 1003.1 specifications for the C API, Shell Utilities, and Threads.
Apple considered several programming languages for the I/O Kit and chose a restricted subset of C++.
The current version of Mac OS is Mac OS X (pronounced "Mac O-S ten").
Even Steve Jobs still says "ecks" instead of "ten" sometimes.
Unsurprisingly, each new Mac OS X release has been the vehicle for a parade of Finder fantasies.
Of course X ("ex") does mean 10, but anyone who used to poke around on Unix systems will know that in those days anything Unix had an X ("ex") in it, and OS Ten is written OS X ("ex") in honour of the fact that it is based on UNIX, unlike its predecessors. So, hey, you can say it any way you want; me, I'm showing my age and sticking with X (ex).
Once you reboot, you'll notice that Apple has abandoned the light and airy Aqua interface for the darker, heavier brushed-metal look of iTunes.
Perhaps one of the announcements that stood out the most was a slight name change. The desktop operating system Mac OS X will now be called macOS to better match with the way the company's other operating systems are named.
As an astrophysicist, having the Unix core underlying the OS is key, since virtually all of our software is Unix-based in some sense
The developers of the Macintosh OS at Apple have always been in this camp [i.e. not trying to be backwards compatible no matter what]. It's why so few applications from the early days of the Macintosh still work...
The next area where Apple claims to have made major improvements is the Finder.
a joint venture with IBM, called Taligent, but was discontinued soon thereafter
Using Mac OS X is like touring a land of fabulous ancient treasures – with a tourist authority that's still busy renovating them, and that hasn't quite completed the infrastructure. The sights can be breathtaking, but the roads are potholed and incomplete, and sometimes you have to get out and push. There are a few magnificent modern additions – Rendezvous, AppleScript Studio, for example – but in places the modern Apple archaeologists seem to have forgotten their ancestors techniques, and have resorted to inferior contemporary methods such as the Windows bodge of using three letter extensions for identifying the file type.
