Before it was replaced with Apple Business Manager, Apple's Device Enrollment Program (DEP) made it easier for businesses to deploy macOS, iOS, and tvOS devices. For example, deploying a device through Apple Business Manager and your Apple MDM solution enables zero-touch deployment, which is automatically applying predefined configurations to devices upon start-up so they can be used right out of the box. As of December 1, 2019, IT administrators can still automatically enroll devices – with no need to physically touch them – they just need to use Apple Business Manager to do it.
