Google Chrome OS Flex: Google does not recommend installing Chrome OS Flex on these Chromebooks

Google recently launched the new Chrome OS Flex, which would give a new lease of life to old Macs and Windows PCs and turn them into Chromebooks. This included devices, which have hit their Auto Update Expiration (AUE) and end-of-life (EOL) date.
The company, however, officially recommends that a user does not install Chrome OS Flex on computers that have reached their AUE/EUL. Google acknowledged that the OS will work but it will not be supported.
According to a report by 9to5 Google, many users, who already use Chromebooks but are not getting any more updates, have already installed Chrome OS Flex. The website reported that some devices, where the OS operated with ease were Acer C720, Asus Chromebox CN60, HP, and Lenovo.
What the Google disclaimer said
Google does not support installing Chrome OS Flex on a Chrome OS device that has reached its AUE date.
While you might be able to install Chrome OS Flex on Intel or AMD x86 Chrome OS devices, we don’t support devices that have reached their AUE date. You might have issues with firmware and hardware compatibility, installation, and updates.
What is ChromeOS Flex?
According to Google, Chrome OS Flex is a new, free-to-download operating system from Google. “Built for businesses and schools, it’s fully compatible with Google’s powerful cloud-based management,” said Google in the blog post. Chrome OS Flex is meant for Mac and Windows PC users who want to use a different OS on their laptops.
Why ChromeOS is a ‘lifeline’ for old laptops?
Since ChromeOS is light and easy to use, it could give a lifeline to old laptops. “Rather than disposing of aging PCs and Macs, refresh them with a modern and fast operating system to reduce e-waste,” said Google in the blog post.
