Apple's mobile operating system, iOS, has been considered a variant of macOS. All releases from Mac OS X 10.5 Leopard and thereafter are UNIX 03 certified, except for OS X 10.7 Lion. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS.The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. In this case I am only compiling the emulator for PPC (32-bit)./configure.MacOS succeeded the classic Mac OS, a Macintosh operating system with nine releases from 1984 to 1999. I have also enabled LibUSB, KVM, HyperVirtualization Framework, and the Cocoa UI. As you can see in OnWorks with Pear OS the developers of this OS have done a wonderful job in imitating Mac OS X and iOS.The kernel of NeXTSTEP is based upon the Mach kernel, which was originally developed at Carnegie Mellon University, with additional kernel layers and low-level user space code derived from parts of BSD. There, the Unix-like NeXTSTEP operating system was developed, and then launched in 1989. In 2020, Apple began the Apple silicon transition, using self-designed, 64-bit ARM-based Apple M1 processors on new Mac computers.The heritage of what would become macOS had originated at NeXT, a company founded by Steve Jobs following his departure from Apple in 1985. In 2006, Apple transitioned to the Intel architecture with a line of Macs using Intel Core processors. After sixteen distinct versions of macOS 10, macOS Big Sur was presented as version 11 in 2020, and macOS Monterey was presented as version 12 in 2021.MacOS has supported three major processor architectures, beginning with PowerPC-based Macs in 1999. Apple shortened the name to "OS X" in 2012 and then changed it to "macOS" in 2016 to align with the branding of Apple's other operating systems, iOS, watchOS, and tvOS.However, it is also commonly pronounced like the letter "X". The letter "X" in Mac OS X's name refers to the number 10, a Roman numeral, and Apple has stated that it should be pronounced "ten" in this context. Mac OS XMac OS X was originally presented as the tenth major version of Apple's operating system for Macintosh computers until 2020, versions of macOS retained the major version number "10". The project was first code named " Rhapsody" and then officially named Mac OS X. This purchase also led to Steve Jobs returning to Apple as an interim, and then the permanent CEO, shepherding the transformation of the programmer-friendly OPENSTEP into a system that would be adopted by Apple's primary market of home users and creative professionals. This led Apple to purchase NeXT in 1996, allowing NeXTSTEP, then called OPENSTEP, to serve as the basis for Apple's next generation operating system.
10.0 Emulator Mac OS X And IOSArs Technica columnist John Siracusa, who reviewed every major OS X release up to 10.10, described the early releases in retrospect as 'dog-slow, feature poor' and Aqua as 'unbearably slow and a huge resource hog'. With Apple's popularity at a low, the makers of several classic Mac applications such as FrameMaker and PageMaker declined to develop new versions of their software for Mac OS X. Reviews were variable, with extensive praise for its sophisticated, glossy Aqua interface, but criticizing it for sluggish performance. Mac OS applications could be rewritten to run natively via the Carbon API many could also be run directly through the Classic Environment with a reduction in performance.The consumer version of Mac OS X was launched in 2001 with Mac OS X 10.0. Consumer releases of Mac OS X included more backward compatibility. As of 20, Apple reverted to Arabic numeral versioning for successive releases, macOS 11 Big Sur and macOS 12 Monterey, as they have done for the iPhone 11 and iPhone 12 following the iPhone X.The first version of Mac OS X, Mac OS X Server 1.0, was a transitional product, featuring an interface resembling the classic Mac OS, though it was not compatible with software designed for the older system. Considering music to be a key market, Apple developed the iPod music player and music software for the Mac, including iTunes and GarageBand. As the operating system evolved, it moved away from the classic Mac OS, with applications being added and removed. Siracusa's review of version 10.3, Panther, noted "It's strange to have gone from years of uncertainty and vaporware to a steady annual supply of major new operating system releases." Version 10.4, Tiger, reportedly shocked executives at Microsoft by offering a number of features, such as fast file searching and improved graphics processing, that Microsoft had spent several years struggling to add to Windows with acceptable performance. While Apple's previous iPod media players used a minimal operating system, the iPhone used an operating system based on Mac OS X, which would later be called "iPhone OS" and then iOS. A key development for the system was the announcement and release of the iPhone from 2007 onwards. In 2006, the first Intel Macs released used a specialized version of Mac OS X 10.4 Tiger. In Leopard, Apple announced a unification of the interface, with a standardized gray-gradient window style. It is also the final release with PowerPC Mac support. In 2007, Mac OS X 10.5 Leopard was the sole release with universal binary components, allowing installation on both Intel Macs and select PowerPC Macs. However, after Apple opened the iPhone to third-party developers its commercial success drew attention to Mac OS X, with many iPhone software developers showing interest in Mac development. This direction was, like brushed metal interfaces, unpopular with some users, although it continued a trend of greater animation and variety in the interface previously seen in design aspects such as the Time Machine backup utility, which presented past file versions against a swirling nebula, and the glossy translucent dock of Leopard and Snow Leopard. Since its release, several OS X or macOS releases (namely OS X Mountain Lion, OS X El Capitan, macOS High Sierra, and macOS Monterey) follow this pattern, with a name derived from its predecessor, similar to the ' tickātock model' used by Intel.In two succeeding versions, Lion and Mountain Lion, Apple moved some applications to a highly skeuomorphic style of design inspired by contemporary versions of iOS while simplifying some elements by making controls such as scroll bars fade out when not in use. The name was intended to signal its status as an iteration of Leopard, focusing on technical and performance improvements rather than user-facing features indeed it was explicitly branded to developers as being a 'no new features' release. Music recording programs for macWith OS X engineers reportedly working on iOS 7, the version released in 2013, OS X 10.9 Mavericks, was something of a transitional release, with some of the skeuomorphic design removed, while most of the general interface of Mavericks remained unchanged. Apple's new user interface design, using deep color saturation, text-only buttons and a minimal, 'flat' interface, was debuted with iOS 7 in 2013. That year, Apple removed the head of OS X development, Scott Forstall, and design was changed towards a more minimal direction. Shifting its focus from large businesses to small ones." OS XIn 2012, with the release of OS X 10.8 Mountain Lion, the name of the system was shortened from Mac OS X to OS X. A review described the trend in the server products as becoming "cheaper and simpler.
