Most Mac users wouldn’t dream of replacing macOS with anything but the latest update, but Google wants you to at least consider another option: Chrome OS.
Chrome OS Flex is a “free and sustainable way” to install Google’s online OS on any Mac or PC. It’s built for schools and businesses looking for “modern computing with cloud-based management.” It offers the same Chrome OS interface as you would get on a Chromebook with “fast access to VDI and web apps with an intuitive, clutter-free, and reliable experience.”
