Performing annual maintenance

Apple MDM Push Certificates, also referred to as APNs certificates, are valid for one year. You must renew the certificate each year using the same Apple ID that you used to create it. If you do not renew your certificate and instead request a new certificate, Mac Device Enrollment loses the ability to communicate with enrolled devices, and all devices must be re-enrolled.

The Apple Push Certificates Portal provides options to renew or to request a new certificate. You must select the option to renew your existing certificate. Otherwise, all users are required to re-enroll their devices.

Before you begin

Make sure you have the credentials for the same Apple ID that you used when you obtained the original Apple MDM push certificate.
