what is the latest version of imac os
macOS Launched in 2001 as Mac OS X, the series is the latest in the family of Macintosh operating systems. Mac OS X succeeded "classic" Mac OS, which was introduced in 1984, and the final release of which was Mac OS 9 in 1999. An initial, early version of the system, Mac OS X Server 1.0, was released in 1999. The first desktop version, Mac OS X 10.0, followed in March 2001. Releases were code named after big cats from the original release up until OS X 10.8 Mountain Lion. Beginning in 2013 with OS X 10.9 Mavericks, releases have been named after landmarks in California.[9] Apple changed the original name "Mac OS X" to "OS X" in 2012 and then to "macOS" in 2016, adopting the nomenclature that it uses for their other operating systems, iOS, watchOS, and tvOS. The latest version of macOS is macOS High Sierra, which was publicly released in September 2017.
macOS version history Mac OS X 10.7 Lion was released on July 20, 2011. It brought developments made in Apple's iOS, such as an easily navigable display of installed applications (Launchpad) and (a greater use of) multi-touch gestures, to the Mac. This release removed Rosetta, making it incapable of running PowerPC applications. It dropped support for 32-bit Intel processors and requires 2GB of memory. Changes made to the GUI (Graphical User Interface) include the Launchpad (similar to the home screen of iOS devices), auto-hiding scrollbars that only appear when they are being used, and Mission Control, which unifies ExposÃ©, Spaces, Dashboard, and full-screen applications within a single interface.[30] Apple also made changes to applications: they resume in the same state as they were before they were closed (similar to iOS). Documents auto-save by default.
OS X El Capitan OS X El Capitan (/ɛl kæpɪˈtɑːn/ el-KAP-ɪ-TAHN) (version 10.11) is the twelfth major release of OS X (now named macOS), Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security.[2] Following the Northern California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park, signifying its goal to be a refined version of Yosemite. El Capitan is the final version to be released under the name OS X; its successor, Sierra, was announced as macOS Sierra. El Capitan received far superior reviews when compared to Yosemite.
iOS 11 iOS 11 is the eleventh major release of the iOS mobile operating system developed by Apple Inc., being the successor to iOS 10. It was announced at the company's Worldwide Developers Conference on June 5, 2017, and released on September 19, 2017.
