what is the latest os update for mac
macOS The fall release of macOS 10.13 High Sierra was announced on June 5, 2017 at Apple's WWDC event.[215] On September 12, 2017 at Apple's iPhone event, they announced its release to be September 25, 2017.[216] Like OS X El Capitan and OS X Mountain Lion, High Sierra is a refinement-based update having very few new features.[217] High Sierra uses the new Apple File System and includes enhancements to Safari, Photos, and Mail, among other changes.[215]
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.
