Enable device-based app assignment to assign volume purchased apps to devices, regardless of whether an Apple ID is active on that device. This is the preferred deployment option for most organizations.
Note that device-based app assignment requires iOS 9 or later or macOS 10.11 or later. App developers can choose to make their app ineligible for device-based assignments, but this is rare.
When deploying volume purchased apps, you have two options for how the app licenses are assigned:
- Volume purchased apps can be synced with the Apple ID that is currently logged in on a device.
- Volume purchased apps can be assigned to the device directly, regardless of the Apple ID on the device
In general, most organizations prefer option 2, as it streamlines the app deployment process. In some situations, organizations may prefer to use option 1, particularly if each user has several Apple devices assigned to them.
