watchOS 27, released September 14, removes the Digital Crown double-click app-switching feature for all Apple Watch models and reserves it exclusively for the new Live Rewind audio transcript feature on Series 12 and Ultra 4. Older model owners lose functionality without gaining the new feature, and Apple offers no option to customize the button assignment or disable Live Rewind.
Apple released iOS 27.2 beta 1, skipping iOS 27.1 beta, featuring a redesigned Health app with new tabs for health insights and longevity tracking, expanded Siri AI language support, CarPlay themes, and new parental controls for Apple TV profiles. The update also includes minor refinements to Clock, Music, and Podcasts apps, plus new accessibility features like sign language interpretation for FaceTime.
