When we hear of Chrome OS versions, we usually stick to the Stable, Beta and Dev versions. I had never heard of the existence of Chrome OS Canary, but it seems it does exist and everyone can access this version.
If you don’t know what Chrome Canary is, it’s pretty much the beta to Chrome Beta. All new developer features and UI changes are sent to Chrome Canary, so there is often a long list of bugs and issues. Chrome OS Canary is not the exception, and it seems it may be even buggier than the desktop version.
Of course, this is not for the faint of heart. Installing Chrome Canary will completely change your experience and bring a slew of problems. Unless you know what you are doing, you may find yourself pulling your hair in frustration.
Known issues include broken external monitor support, hardware issues, half-implemented features and more. What’s worse, it seems it’s really complicated to revert to the Stable version after you have switched to Canary.
Recovery images taken from chrome://imageburner will also be Canary builds if you access it from a Chrome OS Canary device. So unless you have a USB storage device with the stable Chrome OS image, you will be out of luck.
You really have to be sure you want to do this, so make sure you know what you are doing before you act. If you think you are ready, you can find the instructions in the link below.
