Apple Configurator 2 is Apple's one-stop shop to quickly set up and add apps, profiles, and documents to one or many devices in your fleet. Available for free on the Mac App Store, Apple Configurator 2 supports iPhone, iPad, iPod, and Apple TV.
Using Blueprints, setting up an entire fleet of devices can be as simple as setting up just one! Blueprints are templates of a single device, where the installed apps, configuration profiles - such as your Mobile Device Management (MDM) information - and other settings can all be set up once, saved, and re-used on any other devices in your fleet.
You can find step-by-step instructions on how to set up a Fleetsmith MDM Blueprint here.
