Upcoming expiration of Developer ID Certification Authority (Sub-CA)
Apple Developer ID Sub-CA expires February 2027, requiring developer certificate replacement.
Apple's original Developer ID Certification Authority (Sub-CA) expires February 1, 2027, requiring developers to replace affected certificates with new ones from the G2 Sub-CA. This is a routine certificate infrastructure maintenance notice with no AI industry relevance. Developers distributing .pkg installers must re-sign before the deadline; notarized Mac apps with secure timestamps are unaffected.
