Device-assigned managed distribution assigns apps directly to managed devices using Jamf Pro. This method is recommended for institutionally owned devices enrolled via Automated Device Enrollment or Device Enrollment.
Apps you purchase in Apple Business Manager or Apple School Manager sync with Jamf Pro. You can then configure the app's distribution settings, including choosing the volume location that purchased the app, and add devices to the app scope. For more information, see Apps Purchased in Volume.
Keep the following in mind about device-assigned managed distribution:
Apps assigned directly to a device do not require the use of Apple Accounts.
Books cannot be assigned directly to devices and require user-assigned managed distribution.
Users with multiple managed devices require multiple licenses.
If you have apps that were distributed with user-based volume assignments and the apps are device-assignable, you can move to device-based managed distribution for the apps. For more information, see the Moving from User- to Device-based Volume Purchasing Assignments article.
