Apple announced that the Apple Developer certificate will be updated soon. The media certificate of Apple Push Notification Service (APNs) and Developer ID will be updated from January 27, 2022. Among them, the APNs SSL certificate will be issued by the new media certificate (Worldwide Developer Relations G4 sub-CA) specifically for APNs. When the new certificate is activated and available for download, developers can use it to send push notifications to apps (including VoIP), complex features, Safari websites, and Apple wallet passes.
The digital certificate used by developers to sign software and installation packages on macOS will be issued by the new Developer ID media certificate, which will expire on September 16, 2031. The newly issued Developer ID certificate associated with the new media certificate can be used to sign software on Xcode 11.4.1 and later.
If the developer is running Xcode 13.2 or later, the updated certificate will be automatically downloaded when the software is signed after January 28, 2022. If the developer is using an earlier version of Xcode, you can manually download the certificate or create a certificate compatible with the previous version of Xcode.
Apple stated that the developer’s existing certificate will remain valid until it expires or is revoked, whichever comes first.
