Apple macOS

macOS - is the UNIX-based operating system. macOS is created by Apple (previously Apple Computer), starting development in 1984. The Mac OS X (then OS X, now macOS) family was created in 2001, and marked as version 10 (before 2020). It used to be the default operating system on Macintosh computers. macOS is the second most popular computer OS after Microsoft Windows.
Most recent version is macOS Sonoma version 14. It was released on September 26, 2023.
It's rarely used in the OSM community, for a reason of not so original, and having only one major turn, and not so interesting development of modern macOS. In other words, this is not an interesting operating system, which in its base, people can create their own ideas.
==Classic Mac OS==
First ever version is released on January 24, 1984, known as System 1. It gets the Mac OS name starting from version 7.6. Mac OS 7 is the first longest developed version to have only a major number since its release in almost 6 years. The second is Mac OS X starting from 2007. It had a similar interface to Windows.
The term "Classic" started to be used since Apple renamed OS X to macOS in 2016, which would not get people confused.

==Mac OS X Versions==
macOS was developed from NeXTSTEP in 1997, and on March 16, 1999, Apple had released Mac OS X Server 1.0, which was the first way to the Mac OS X era. Then they released the public beta on September 13, 2000, revealing some features like Dock, menu bar, and new interface. Tiger is the first release to adopt Intel processors and the x86 architecture in general. Mac OS X was released publicly on March 24, 2001 as version 10.0, then renamed to OS X starting from version 10.8, then to macOS in 10.12. While Microsoft and the majority of OS creators hide their codenames, Apple uses codenames in macOS starting from 10.0, naming a new codename every version. They name macOS codenames from versions 10.0-10.8 after big cats, while since 10.9 they name them after major California landmarks. The last version of macOS was released in early October, with macOS 10.15, released on October 7, 2019.
The last version of macOS to support only Intel processors had its final update on July 20, 2022 (to be confirmed).
