[106], In April 2002, eWeek announced a rumor that Apple had a version of Mac OS X code-named Marklar, which ran on Intel x86 processors. [30] Considering music to be a key market, Apple developed the iPod music player and music software for the Mac, including iTunes and GarageBand. [230] Updates included enhanced voice control, and bundled apps for music, video, and podcasts that together replace the functions of iTunes, and the ability to use an iPad as an external monitor. [138][139] macOS makes use of a Dock, which holds file and folder shortcuts as well as minimized windows. --- System .97 (known as 1.0) / Finder 1.0: first real Macintosh operating system. [222] Refinements include public transport built into the Maps application, GUI improvements to the Notes application, adopting San Francisco as the system font for clearer legibility, and the introduction of System Integrity Protection. Snow Leopard only supported machines with Intel CPUs, required at least 1 GB of RAM, and dropped default support for applications built for the PowerPC architecture (Rosetta could be installed as an additional component to retain support for PowerPC-only applications). [55], At macOS's core is a POSIX-compliant operating system built on top of the XNU kernel, [56] with standard Unix facilities available from the command line interface. [184][185] Computer retailer Tiger Direct sued Apple for its use of the name "Tiger". OS X ran on a UNIX kernel (core software code) and offered technical advances such as memory protection and preemptive multitasking, along with a more versatile Finder, an elegant-looking interface called Aqua, and a convenient graphical “Dock” bar for launching frequently used applications. New interface elements were integrated, including sheets (dialog boxes attached to specific windows) and drawers, which would slide out and provide options. [20][21] However, it is also commonly pronounced like the letter "X".[21][22]. What is the operating system made by Microsoft? The simultaneous release of two operating systems based on the same frameworks placed tension on Apple, which cited the iPhone as forcing it to delay Mac OS X 10.5 Leopard. Intel-based Macs would run a new recompiled version of OS X along with Rosetta, a binary translation layer which enables software compiled for PowerPC Mac OS X to run on Intel Mac OS X machines. It brought developments made in Apple's iOS, such as an easily navigable display of installed applications called Launchpad and a greater use of multi-touch gestures, to the Mac. Following some bug fixes, kernel panics became much less frequent. The heritage of what would become macOS had originated at NeXT, a company founded by Steve Jobs following his departure from Apple in 1985. Jobs also confirmed rumors that Apple had versions of Mac OS X running on Intel processors for most of its developmental life. [227] Like OS X El Capitan and OS X Mountain Lion, High Sierra is a refinement-based update having very few new features visible to the user, including updates to Safari, Photos, and Mail, among other changes. Xcode provides interfaces to compilers that support several programming languages including C, C++, Objective-C, and Swift. Application pop-ups are now concentrated on the corner of the screen, and the Center itself is pulled from the right side of the screen. [87], Applications can be distributed to Macs and installed by the user from any source and by any method such as downloading (with or without code signing, available via an Apple developer account) or through the Mac App Store, a marketplace of software maintained by Apple through a process requiring the company's approval. [47] Apple's 2015 update, OS X 10.11 El Capitan, was announced to focus specifically on stability and performance improvements. macOS (/ˌmækoʊˈɛs/;[8] previously Mac OS X and later OS X) is a series of proprietary graphical operating systems developed and marketed by Apple Inc. since 2001. Updates? [241] In early 2011, Mac OS X experienced a large increase in malware attacks,[242] and malware such as Mac Defender, MacProtector, and MacGuard were seen as an increasing problem for Mac users. [32] In Leopard, Apple announced a unification of the interface, with a standardized gray-gradient window style. Save 50% off a Britannica Premium subscription and gain access to exclusive content. In 2009, Apple announced at WWDC that Mac OS X 10.6 Snow Leopard would drop support for PowerPC processors and be Intel-only. [191] Simply releasing Mac OS X was received by the Macintosh community as a great accomplishment,[191] for attempts to overhaul the Mac OS had been underway since 1996, and delayed by countless setbacks. Carbon was not included in the first product sold as Mac OS X: the little-used original release of Mac OS X Server 1.0, which also did not include the Aqua interface. [100] Among the new features, Tiger introduced Spotlight, Dashboard, Smart Folders, updated Mail program with Smart Mailboxes, QuickTime 7, Safari 2, Automator, VoiceOver, Core Image and Core Video. [44] The next version, OS X 10.10 Yosemite, adopted a design similar to iOS 7 but with greater complexity suitable for an interface controlled with a mouse. Quartz's internal imaging model correlates well with the Portable Document Format (PDF) imaging model, making it easy to output PDF to multiple devices. That version also introduced Spaces, a virtual desktop implementation which enables the user to have more than one desktop and display them in an Exposé-like interface;[146] an automatic backup technology called Time Machine, which allows users to view and restore previous versions of files and application data;[147] and Screen Sharing was built in for the first time. [140] FileVault is optional encryption of the user's files with the 128-bit Advanced Encryption Standard (AES-128). ), including Quartz Extreme for compositing graphics directly on an ATI Radeon or Nvidia GeForce2 MX AGP-based video card with at least 16 MB of VRAM, a system-wide repository for contact information in the new Address Book, and an instant messaging client named iChat. In macOS 10.14 Mojave, the updating function was moved again to the Software Update preference pane. Numerous other developers also offer software for macOS. With the exception of Mac OS X Server 1.0 and the original public beta, OS X versions were named after big cats until OS X 10.9 Mavericks, when Apple switched to using California locations. Apple has released this family of software as a free and open source operating system named Darwin. This technology, introduced in version 10.2, is called Quartz Extreme, a component of Quartz. At first, the malware installer required the user to enter the administrative password, but later versions installed without user input. [53] It was succeeded by macOS 10.15 Catalina in 2019, which replaces iTunes with separate apps for different types of media, and introduces the Catalyst system for porting iOS apps. 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. Its graphical user interface was built on top of an object-oriented GUI tool… Catalina officially dropped support for 32-bit applications. Disks had an "Empty Folder" - new folders were created by changing the name of the Empty Folder - a replacement Empty Folder would immediately appear. macOS 10.15 Catalina was released on October 7, 2019. 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. Leopard is an Open Brand UNIX 03 registered product on the Intel platform. Note: The headings on this list indicate the Macintosh System bundle names; the bullet points indicate the version of the System File included in that bundle. Support for the PowerPC platform was dropped following the transition. [154] Recent updates have added increased support for Chinese characters and interconnections with popular social networks in China.[155][156][157][158]. The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services. [125] As a side result, PDF viewing and creating PDF documents from any application are built-in features. [61] More recently, another Macworld editor, Dan Frakes, called the procedure of repairing permissions vastly overused. "Panther", "Tiger" and "Leopard" are registered as trademarks of Apple,[181][182][183] but "Cheetah", "Puma" and "Jaguar" have never been registered. [17] The OS was introduced in 1984 to run the company’s Macintosh line of personal computers (PCs).
