#macOS is an exclusive operating system developed by Apple for the Mac series products. macOS is the pre-installed system for Apple's Mac series products, embodying the purpose of simplicity everywhere.

macOS is the world's first comprehensive operating system based on the FreeBSD system that adopts an "object-oriented operating system". The "object-oriented operating system" was developed by NeXT, a company founded by Steve Jobs in 1985 after he was forced to leave Apple. Later Apple acquired NeXT. Steve Jobs returned as CEO of Apple, and the Mac OS system that Mac began to use was integrated into the Openstep system developed by NeXT.

The latest official version is macOS Catalina.

The letter "X" is a Roman numeral and is officially pronounced "ten" (ten), continuing the numbering of previous Macintosh operating systems such as Mac OS 8 and Mac OS 9. The reason why some people mistakenly pronounce it as the letter "X" and pronounce it as "ex" is that the traditional naming of Unix-like operating systems ends with the letter x (such as AIX, IRIX, Linux, Minix, Ultrix, Xenix). Another reason is Apple's tendency to refer to specific versions as (for example) "Mac OS X version 10.4" in print. [2]

OS X v10.0-10.8 versions are codenamed after big cats within Apple computers. For example, version 10.0 is codenamed Cheetah, and version 10.1 is codenamed Puma. After version 10.2 of Apple's product market, Apple publicly used his feline name as a product trademark to launch the system and as the abbreviation of the system version. Because Jobs thought that everyone was very interested in the internal code name of the previous version, he used it to register the trademark. Made public. Mac OS X 10.2 is named Jaguar, and 10.3 is similarly named Panther. In 2011, Apple launched OS X Lion and changed the naming rules, removing the word Mac and version number from the official product name. OS X Mountain Lion was launched in 2012. Now that feline names are running out, when OS X Mavericks was released at WWDC 2013, Craig Federighi joked that OS X 10.9 had considered naming it OS A surfing spot in the north. He then announced that in the next ten years, Apple will use the names of California attractions that inspired the development team as system code names, such as OS X Yosemite released in 2014. "Yosemite" is California's "Yosemite National Park."

Because Apple used the name "Tiger" in version 10.4, TigerDirect, a computer retailer whose brand name contains the word "Tiger", filed a legal lawsuit against Apple. However, on May 16, 2005, a Florida federal court ruled that Apple Computer's use of the "Tiger" name did not infringe TigerDirect's trademark. [2]
