My sportsclub have several av these Chromebox'es but they will not run some javascript on some important webpages. It sort of looks these Chromeboxes will not upgrade any more.
I check status on its "About Chrome OS" and it says "Chromebox unit updated. Version 76.0.3809.136". Also, "Firmware = Google_Zako.5219.30.0".
Latest is 119 today. That is why simple things, like "mystring".replaceAll(...); is not working on this box.
Is there a way, or how can I upgrade this box to newer ChromeOS versions?
