Upgrade to macOS Big Sur

MacOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.' S desktop operating system for Macintosh computers. MacOS High Sierra was announced at the WWDC 2017 on June 5, 2017 and was released on September 25, 2017. Download macOS Big Sur If you’re using macOS Mojave or later, choose Apple menu System Preferences, then click Software Update. If you’re using an earlier macOS, use the App Store instead. Apple's MacOS High Sierra update offers lots of behind-the-scenes changes that should make the Apple's desktop OS easy to use. High Sierra might disappoint those looking for whizzy new features. Apple previewed macOS 10.13 High Sierra at WWDC 2017, before releasing it later that year. When running on solid state drives, it uses APFS, rather than HFS+. Its successor, macOS 10.14 Mojave, was released in 2018, adding a dark user interface option and a dynamic wallpaper setting.
