Mountain Brook Chromebooks can only be signed in with a Mountain Brook Google Apps Account.  You may not use a personal Google Account. A managed Chromebook is set up and maintained by a school or company.  If you see the  managed icon in the status area in the lower right-hand side of your screen when you’re signed in to your Chromebook, your device is managed.

Using a Managed Chromebook

When you sign in to a managed Chromebook, some features are already set up for you. Your network administrator can install apps, set up printers, and manage how you use your Chromebook.
