Requirements
To set a device to Single App Mode, you need a supervised iPad or iPhone with iOS 9 or later, or supervised Apple TV with tvOS 9 or later. For more information on supervised devices, see Supervision.
You can only enable Single App Mode for apps managed by Jamf Now, as well as unmanaged built-in system apps, such as Books, Music, and Safari. Single App Mode cannot be applied to user-installed apps.
Note:
You should not push OS updates after putting a device in Single App Mode. Ensure that all updates are complete before placing a device into this mode. For more information, see OS Updates.
