Supervised configuration (fully managed devices):
This is for company-owned Apple devices. They are automatically configured with apps and settings. It is also set as the default DEP profile, meaning any device assigned in ABM will automatically receive this profile and be ready to use right out of the box.
Unsupervised configuration (personal devices):
This is for privately owned devices that are already set up. These devices can be managed by downloading and installing the Apple unsupervised enrollment profile. Once enrolled, apps and configurations are automatically installed on the device.
