Encountering the “This certificate has an invalid issuer” error when adding a certificate for Apple Push Services can be a frustrating experience. This issue typically arises due to expired certificates in your Keychain Access, particularly affecting the Apple Worldwide Developer Relations Intermediate Certificate. This guide will walk you through resolving this issue effectively.

Step-by-Step Solution

To resolve the “invalid issuer” error, follow these steps:

1. Open Keychain Access on your macOS device.
2. Navigate to View → Show Expired Certificates to ensure all certificates, including expired ones, are visible.
3. In the Login Keychain, locate and delete the expired Apple Worldwide Developer Relations Certificate Authority certificate.
4. Repeat the deletion process in the System Keychain.
5. Download the new WWDR Intermediate Certificate from the official Apple Developer website.
6. Double-click the downloaded certificate to install it into your Keychain.
7. Verify that the newly installed certificate appears as valid by checking its status in Keychain Access.

By following these steps, your certificates should now be valid, allowing you to proceed with your app development and distribution processes without interruption.

Additional Tips

If you continue to experience issues, ensure that your system’s date and time settings are correct, as discrepancies can sometimes cause certificate validation errors.
