The Administrator role in Apple Business Manager holds the highest level of privileges, granting the ability to perform all available tasks. This comprehensive access includes both purchasing apps and books (content management) and assigning devices to a linked Mobile Device Management (MDM) server. Other default roles are specialized and do not possess this combination of permissions. The principle of least privilege is applied to other roles, separating content, device, and people management functions to enhance security and operational clarity.

B. Content Manager: This role is specifically for purchasing and managing licenses for apps and books but does not have the permissions to assign devices to an MDM server.

C. Device Enrollment Manager: This role is focused on managing MDM servers and assigning devices to them but lacks the privileges to purchase content like apps and books.

D. People Manager: This role is responsible for creating and managing user accounts (Managed Apple IDs) and roles but has no permissions related to device assignment or content purchasing.

1. Apple Inc.

Apple Business Manager User Guide. "Roles and privileges in Apple Business Manager" section. This official guide explicitly states that an Administrator "can perform all tasks in Apple Business Manager

" which encompasses the duties of all other roles

including purchasing content and assigning devices. It also details the limited

specific permissions of the Content Manager and Device Enrollment Manager roles.

2. Stanford University IT Services

Apple at Stanford: Apple Business Manager (ABM) Roles. This university documentation outlines the responsibilities for each role

confirming that the Administrator has "full access to all features

" while the Content Manager is limited to "purchase and manage app and book licenses" and the Device Enrollment Manager is limited to "manage MDM servers and assign devices." This aligns with the principle of separated duties for non-administrator roles.
