Apple has released macOS 11.7.11, watchOS 10.6.2, and watchOS 9.6.4 for older Macs and Apple Watches that cannot run macOS 26 or watchOS 26. These updates keep key services like device activation, iMessage, and FaceTime working past January 2027, so users do not lose access on older hardware.
Apple explained in its release notes that the updates are meant to extend the certificate used by features like device activation, iMessage, and FaceTime. This certificate change ensures these services continue to work after January 2027.

macOS 11.7.11 is for older Macs that cannot move to macOS 26. Apple also released macOS Catalina Security Update 2026-001 and watchOS 6.3.1 for even older devices.
