Add Device Enrollment & Volume Purchase Program

Apple Business Manager combines Device Enrollment Program and Volume Purchase Program in one console. Depending on your preferences configure either Device Enrollment Program or Volume Purchase Program or both. Both has a part that needs to be done in Business Manager and a part for Silverback. 

Device Enrollment Program

Apple's Device Enrollment Profile (DEP) program automates mobile device management (MDM) enrollment. Using DEP, you can configure enterprise devices without touching them. To configure the Device Enrollment Program we will need to create a public key, add your Silverback Server in Apple Business Manager and import the trusted server token into Silverback. 

Create your Public Key

For creation of  a Public Key for your Device Enrollment Program you'll need the following: 

  • Mac Computer with latest macOS and
    • Apple macOS Keychain application (built-in)
    • Apple macOS Terminal application (built-in)
    • Apple macOS TextEdit application (built-in)

If your organization should not have an Apple macOS computer, please contact Matrix42 Support or your Matrix42 Partner Consultant.

Next Steps

Volume Purchase Program

Volume Purchase Program provides IT Administrators an easy way to find, purchase, and distribute Apps and Books in volume for the entire organization.

Before your start

Before you start please note the following criteria:

  • If you previously used a VPP token with a different product, you must generate a new one 
  • A VPP token is only supported for use in one MDM System at time. Do not reuse the same VPP token for multiple MDM Systems
  • Tokens are valid for one year
  • Before you start to use Apple VPP with Silverback, remove any existing VPP user accounts created with other mobile device management (MDM) vendors. 
  • We recommend to use the Device only  as VPP Operation mode.  When you assign VPP apps using the user licensing model to users or devices (with user affinity), each user needs to be associated with a unique Apple ID or an email address when they accept the Apple terms and conditions on their device. Ensure that when you set up a device for a new Silverback user, you configure it with that user's unique Apple ID or email address. The Apple ID or email address and Silverback user form a unique pair and can be used on up to five devices.
  • By default, Silverback synchronizes with the Apple VPP service in a given period to refresh.  A manual sync is possible at any time.
