How to Install Chrome OS Flex on an Old Mac

Ever wanted to use a Google Chromebook running Chrome OS? If you have an old MacBook that isn’t fast enough already, you can install Google Chrome OS Flex on it, which will turn your old Mac into a Chromebook.

One of the advantages of the Mac is that the macOS operating system receives security updates for a rather long time, however, sooner or later support for older Macs stops and they stop receiving updates. There is a way out – to use a third-party operating system, for example, based on the Chrome web browser from Google – Chrome OS Flex. Perhaps it will give your old Mac a new life.

There is one downside, you will have to erase your current macOS operating system in order to install Chrome OS Flex on an old Mac.

Google Chrome OS Flex supports any Mac from 2010 and newer, so you can run Chrome OS on an older device that Apple no longer supports.

To install a Chromebook, you’ll need an 8GB or larger USB flash drive (which will become your Chrome OS installation disc), Chrome Web Browser (the installer is located here), a 2010 or newer Mac with at least 16GB of RAM.
