It is possible to install High Sierra on many older Macintosh computers that are not officially supported by Apple. This requires using a patch to modify the install image.
Deprecation of 32-bit support
Apple notified developers that High Sierra would be the last version of macOS to run 32-bit applications "without compromise". Starting with the update to macOS 10.13.3, launching a 32-bit application would display an alert that it "is not optimized for your Mac. This app needs to be updated by its developer to improve compatibility." macOS Mojave (10.14) would be the final major release to even run 32-bit software at all. MacOS Catalina (10.15) would mark the completion of Apple's transition to 64-bit technology and no longer support 32-bit applications.
Development and release
The first beta of macOS High Sierra was released to developers shortly after the keynote of the 2017 Worldwide Developers Conference on June 5. The new features were presented by Craig Federighi, the senior VP of software engineering. When discussing how the "crack marketing team" came up with the name High Sierra while traveling in their minibus, he joked that they "assured us this name is fully baked."
The first public beta was made available in July 2017. macOS High Sierra was officially launched on September 25, 2017, as a free downloadable upgrade through the Mac App Store. There is no physical retail version from Apple, though it is possible to create a bootable drive of the installer.
