This logo was used for the Mac OS X v10.0, code-named 'Cheetah', and v10.1, code-named 'Puma'. Released on March 23, 1995. The Mac OS logo and rebranding marks its debut on version 7.5.1. The Happy Mac icon was the normal bootup screen of the Macintosh, it was also used on floppy disks of System softwares.

You’ll need the following: OS X 10.9 or later 4GB of memory 35.5GB available storage on macOS Sierra or later Some features require an Apple ID terms apply.Although 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. If your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Big Sur. 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.Before you upgrade, we recommend that you back up your Mac. 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. You can also use it to make online purchases thanks to Apple Pay on the web.The history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2012 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS.The operating system was further renamed to "macOS" starting with macOS Sierra.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 10.0–10.8) or locations in California (10.9–present).A new macOS - Monterey was announced during WWDC on June 7, 2021.Diagram of the relationships between Unix systems including the ancestors of macOSAfter 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. 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. (Many text editors, like BBEdit and Atom, have their own CLI tool, but if they don’t, you can use open -t instead.)It 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.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. Restore wd my passport for macAll but abandoning the idea of an operating system, NeXT managed to maintain a business selling WebObjects and consulting services, but was never a commercial success. 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. Traces of the NeXT software heritage can still be seen in macOS. (Some of these efforts, such as Taligent, did not fully come to fruition others, like Java, gained widespread adoption.) On February 4, 1997, Apple Computer acquired NeXT for $427 million, and used OPENSTEP as the basis for Mac OS X, as it was called at the time. However, by this point, a number of other companies — notably Apple, IBM, Microsoft, and even Sun itself — were claiming they would soon be releasing similar object-oriented operating systems and development tools of their own. OPENSTEP was, for a short time, adopted by Sun Microsystems. The decade-old Macintosh System Software had reached the limits of its single-user, co-operative multitasking architecture, and its once-innovative user interface was looking increasingly outdated.

Some elements of Copland were incorporated into Mac OS 8, released on July 26, 1997.After considering the purchase of BeOS — a multimedia-enabled, multi-tasking OS designed for hardware similar to Apple's, the company decided instead to acquire NeXT and use OPENSTEP as the basis for their new OS. By 1996, Copland was nowhere near ready for release, and the project was eventually cancelled. The board asked Steve Jobs to lead the company on an interim basis, essentially giving him carte blanche to make changes to return the company to profitability. This "rejection" of Apple's plan was largely the result of a string of previous broken promises from Apple after watching one "next OS" after another disappear and Apple's market share dwindle, developers were not interested in doing much work on the platform at all, let alone a re-write.Apple's financial losses continued and the board of directors lost confidence in CEO Gil Amelio, asking him to resign. Instead, several major developers such as Adobe told Apple that this would never occur, and that they would rather leave the platform entirely. The result was known by the code name Rhapsody, slated for release in late 1998.Apple expected that developers would port their software to the considerably more powerful OPENSTEP libraries once they learned of its power and flexibility. During this time, the lower layers of the operating system (the Mach kernel and the BSD layers on top of it ) were re-packaged and released under the Apple Public Source License. Support for C, C++, Objective-C, Java, and Python were added, furthering developer comfort with the new platform. Meanwhile, applications written using the older toolkits would be supported using the "Classic" Mac OS 9 environment. Mac OS applications could be ported to Carbon without the need for a complete re-write, making them operate as native applications on the new operating system. Over the next two years, major effort was applied to porting the original Macintosh APIs to Unix libraries known as Carbon. This consisted of porting a high-speed Java virtual machine to the platform, and exposing macOS-specific "Cocoa" APIs to the Java language. During this period, the Java programming language had increased in popularity, and an effort was started to improve Mac Java support. The Darwin kernel provides a stable and flexible operating system, which takes advantage of the contributions of programmers and independent open-source projects outside Apple however, it sees little use outside the Macintosh community.
