Updating Chrome
Normally chrome keeps itself relatively up-to-date through automatic updates. There are cases, specially with rarely used chromebooks, where a manual update is necessary. This has been known to solve issues with M-step testing due to out-of-date chrome.
After opening chrome click on the three dots in the upper right of the window. From there select Settings
On the settings page in the side bar at the bottom select About Chrome
Click on Update Chrome if you cant find this button you are on the latest version of chrome
After any updates have finished installing, a restart of the application may be required. Your chrome build will now be up to date.
