Get an Apple MDM push certificate
An Apple MDM Push certificate is required for Intune to manage iOS and macOS devices. After you add the certificate to Intune, your users can enroll their devices using:
The Company Portal app.
Apple's bulk enrollment methods like the Device Enrollment Program, Apple School Manager, or Apple Configurator.
For more information about enrollment options, see Choose how to enroll iOS devices.
When a push certificate expires, you must renew it. When renewing, make sure to use the same Apple ID that you used when you first created the push certificate.
