Apple previewed macOS High Sierra on June 5, 2017, the latest version of the world’s most advanced desktop operating system, delivering new core storage, video, and graphics technologies that pave the way for future innovation on the Mac.
(Clarification: after the second download started, I did have an 'OS X El Capitan' entry in my purchase history on the Snow Leopard computer.) Copied the macOS Sierra and El Capitan installers to my file server. On my current Mac, copied Install OS X El Capitan.app to my /Applications directory. Ran the Install OS X El Capitan app.
macOS High Sierra offers an all-new file system, support for High-Efficiency Video Coding (HEVC) and an update to Metal, Apple’s advanced graphics technology that powers everything from machine-learning to virtual reality content creation.
