This guide describes how to create, renew, or delete an Apple push certificate. You must have a push certificate in Jamf School to manage devices with Jamf School. Devices enrolled prior to May 2, 2017 are managed by a push certificate in Jamf School. To check if your devices are managed by Jamf School, navigate to Organization > Settings > Apple Push Notification Service. If the Push Topic is “com.apple.mgmt.XServer.01ab0995-0663-4e2d-a001-25e9ef3eaf9e”, the devices are currently managed by Jamf School. You must create your own certificate for future enrollments. If a new certificate is created, enrolled mobile devices will not be able to receive MDM commands unless they are re-enrolled. Apple requires the Apple Push Notification service (APNs) certificate to be renewed every year.
Important: If the original Apple push certificate expires or is deleted, you must manually re-enroll all managed devices.
