How to update Google Chrome
Your MacBook has permissions set so that you can update Google Chrome without any need from ICT in most cases.
When you see the update notification in Google Chrome you can click on the Update button in the corner.

Then select Relaunch to Update Chrome.
In some cases if it has been a while or in the case of a major Chrome update, it may require a full installation. If you get an error message, please submit a ticket so that ICT can make arrangements to assist with the update.
