ДЄll but abandoning the idea of an operating system, NeXT managed to maintain a business selling WebObjects and consulting services, only ever making modest profits in its last few quarters as an independent company.

It also supported the innovative Enterprise Objects Framework database access layer and WebObjects application server development environment, among other notable features.

This environment is known today in the Mac world as Cocoa. It featured an object-oriented programming framework based on the Objective-C language. NeXTSTEP was based on the Mach kernel developed at CMU (Carnegie Mellon University) and BSD, an implementation of Unix dating back to the 1970s. The hardware was phased out in 1993 however, the company's object-oriented operating system NeXTSTEP had a more lasting legacy. As the first workstation to include a digital signal processor (DSP) and a high-capacity optical disc drive, NeXT hardware was advanced for its time, but was expensive relative to the rapidly commoditizing workstation market and marred by design problems. ДЄ diagram of the relationships between Unix systems including the ancestors of macOSДЄfter Apple removed Steve Jobs from management in 1985, he left the company and attempted to create the 'next big thing', with funding from Ross Perot and himself. The current major version, macOS 12 Monterey, was announced in WWDC 2021 and released on October 25 of that year the latest version of macOS 12, macOS 12.3, was released on March 14, 2022. MacOS retained the major version number 10 throughout its development history until the release of macOS 11 Big Sur in 2020 releases of macOS have also been named after big cats (versions 10.0вЂ“10.8) or locations in California (10.9вЂ“present). The operating system was further renamed to 'macOS' starting with macOS Sierra. Lion was sometimes referred to by Apple as 'Mac OS X Lion' and sometimes referred to as 'OS X Lion', without the 'Mac' Mountain Lion was consistently referred to as just 'OS X Mountain Lion', with the 'Mac' being completely dropped.

Starting with the Intel build of Mac OS X 10.5 Leopard, most releases have been certified as Unix systems conforming to the Single Unix Specification. Starting with Mac OS X 10.7 Lion, macOS Server is no longer offered as a separate operating system instead, server management tools are available for purchase as an add-on. Since then, several more distinct desktop and server editions of macOS have been released. MacOS was first released in 1999 as Mac OS X Server 1.0, with a widely released desktop version- Mac OS X 10.0-following in March 2001. To ease the transition, versions through 10.4 were able to run Mac OS 9 and its applications in a compatibility layer. The transition was a technologically and strategically significant one.

However, the current macOS is a Unix operating system built on technology that had been developed at NeXT from the 1980s until Apple purchased the company in early 1997.ДЄlthough it was originally marketed as simply 'version 10' of the Mac OS (indicated by the Roman numeral 'X'), it has a completely different codebase from Mac OS 9, as well as substantial changes to its user interface. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Macintosh computers since their introduction in 1984.
