An Apple MDM Push certificate is required for Intune to manage Apple devices (iOS/iPadOS & macOS). After we add the certificate to our Intune tenant, our users can enroll their devices using:

• The Company Portal app or
• Apple’s bulk enrollment methods like ADE

To Set up the MDM Push certificate –

Go to Devices -> Enroll devices -> Apple Enrollment 

Click on Apple MDM Push Certificate

Tick the check box I agree (To give Microsoft permission to send data to Apple.) in Step 1.

Click on Download your CSR to download and save the request file locally (The file is used to request a trust relationship certificate from the Apple Push Certificates Portal) in Step 2.

Go to Step 3 and Click on Create your MDM push Certificate  to go to the Apple Push Certificates Portal

Sign in with your Apple ID.

(Record this ID as a reminder for when you need to renew this certificate.)

Click on Create yours now to create a new Apple ID, if you don’t have one already.

Note: Make sure to use or create an Enterprise account rather than a personal Apple ID. Keep in mind that the account you use should be one that is easily shared or transferred in the case that the person setting up the MDM push Certificate leaves the company or moves teams.

Click on Create a Certificate.

Tick the check box I have read and agree to these terms and conditions.

And click on Accept button.

Select Choose File and browse to the CSR (certificate signing request) file downloaded in step 2.

and then choose Upload.

On the Confirmation page, choose Download to download the certificate (.pem) file and save the file locally.

Now Go to Intune portal again and Enter the Apple ID (used to create your Apple MDM push certificate) in step 4.

Now go to step 5, Click on Select a file under “Browse to your Apple MDM push certificate to upload” section, select the certificate (.pem) file, choose Open, and then choose Upload.

And your MDM Push certificate Setup is complete.

You can check the certificate details by Clicking on Apple MDM Push certificate.

Now you see, all the enrollment methods and options are available to configure.

Note:

1. The Apple MDM push certificate is valid for one year and must be renewed annually to maintain iOS/iPadOS and macOS device management. If your certificate expires, enrolled Apple devices cannot be contacted.

2. 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. If you request a new certificate instead of renewing your existing certificate, you will be forced to unenroll and re-enroll all of your existing iOS devices. 

Renew Apple MDM Push Certificate

In Intune Portal, go to Devices -> Enroll devices -> Apple Enrollment 

Click on Apple MDM Push Certificate

Click on Download your CSR to download and save the request file locally in Step 2.

Go to Step 3 and click on Create your MDM push Certificate  to go to the Apple Push Certificates Portal or click on https://identity.apple.com/pushcert/

Sign in with the same Apple ID that you used when you first created the push certificate.

Find the certificate you want to renew and select Renew.

On the Renew Push Certificate screen, provide notes to help you identify the certificate in the future, select Choose File to browse to the new request file you downloaded, and choose Upload.

On the Confirmation screen, select Download and save the .pem file locally.

Now Go to Intune portal again and Enter the Apple ID (used to create your Apple MDM push certificate) in step 4.

In step 5, Click on Select a file under “Browse to your Apple MDM push certificate to upload” section, select the certificate (.pem) file, choose Open, and then choose Upload.

Your Apple MDM push certificate appears Active and has 365 days until expiration.

Note: A Certificate can be identified by its UID. Examine the Subject ID in the certificate details to find the GUID portion of the UID.

Or on an enrolled iOS/iPadOS device, go to Settings > General > Device Management > Management Profile > More Details > Management Profile. The second line item, Topic, contains the unique GUID that you can match up to the certificate in the Apple Push Certificates portal.
