Plan for content distribution in Apple Business Manager
App and book distribution works best when content is assigned before devices are configured or given to users. After the user receives the device and completes the Setup Assistant, your mobile device management (MDM) solution can send the user an invitation by email or push notification. When the user accepts the invitation, the user has access to all the MDM-assigned content — which your MDM solution can install on the user’s device remotely.
To simplify your deployment, it is highly recommended that you assign apps to devices instead of users. With device-based app assignment, there is no invitation process or requirement to use an Apple ID on the device. Books cannot be assigned to devices.
Note: In-app purchases are not compatible with apps assigned to a device.
To preserve bandwidth during the initial mass deployment, consider distributing only the apps needed for the first day of deployment, and then make additional apps available to users for download over time. If the device is supervised, apps are installed silently by your MDM solution.
Apps that are assigned to a device through your MDM solution:
may be automatically removed when a user un-enrols the device from MDM
This also applies to user-assigned apps.
are not automatically re-installed after a backup from the Finder (in macOS 10.15 or later), iTunes (in macOS 10.14 or earlier) or iCloud restore from backup.
Note: To learn whether purchasing content in volume is available in your country or region, see the Apple Support article Availability of Apple programmes and payment methods for education and business.
