User Enrollment is the Apple MDM framework specifically designed for Bring Your Own Device (BYOD) deployments. It prioritizes user privacy by separating corporate data from personal data on a single device. This is achieved by creating a separate, managed APFS volume for work apps and data linked to a Managed Apple ID. This model provides the organization with sufficient control over its own data and configurations while restricting its ability to view personal information or perform intrusive actions, such as a full device wipe. This separation is fundamental to the trust and adoption required in a BYOD environment.

A. Device: "Device Enrollment" is a more general term for manually enrolling a device into MDM. While technically used in some BYOD cases, User Enrollment is the modern, purpose-built, and more common method that offers better privacy protections.

C. Automated device: Automated Device Enrollment (ADE) is exclusively for institutionally owned devices. It provides a higher level of mandatory, non-removable management and supervision that is inappropriate for personally owned hardware.

Reference Detail: The section "User Enrollment" explicitly states

"User Enrollment is designed for bring your own device (BYOD) — where the device is owned by the user

not the organization." The section "Automated Device Enrollment" states

"Automated Device Enrollment is designed for devices owned by the organization."

Reference Detail: This document details the technical implementation

stating

"For personally owned devices

User Enrollment provides a subset of management settings... This separation is accomplished by a managed Apple ID

user enrollment profile

and a separate volume on the device for managed apps and data."

Reference Detail: In the "Enrollment for Personally-Owned Devices" section

the university outlines a process consistent with Apple's User Enrollment framework

emphasizing that for personal devices

management is limited to "university data and settings" and does not allow access to personal data

which aligns with the principles of User Enrollment for BYOD.
