Google today announced in a blog post that ChromeOS Flex, a version of its Chromebook operating system suitable for most hardware, has moved from early access to general availability. It also said it certified "over 400" devices, including systems from Apple, Dell, and HP, to run the OS smoothly and stably.

Google announced ChromeOS Flex in February, building upon its 2020 acquisition of CloudReady (CloudReady becomes ChromeOS Flex now that the latter is stable). Cloud OS Flex is downloadable to a USB drive for free, allowing you to install it on a Mac or Windows PC.
