Apple makes first public beta builds available for iOS 27.3, iPadOS 27.3, macOS Golden Gate 27.3, and also tvOS 27.3 and watchOS 27.3. The public releases follow earlier developer betas released just days before, and outlets note that early software can include bugs and potential incompatibilities.
Coverage highlights a set of feature additions across platforms. MacRumors and 9to5Mac describe iOS 27.3 as including a Vertical Tabs option and Adaptive Dark Mode for Safari, expanded Siri capabilities across Apple apps, and new options in a redesigned Health app with custom insights and Longevity information. They also point to Apple Music changes, iPhone Duo-related updates, and Apple Watch testing features such as Live Rewind and Siri Recap. MacRumors adds that macOS Golden Gate 27.3 brings Safari features and Live Activities to Macs without a Dynamic Island.
AppleInsider emphasizes caution for mission-critical users, pointing to bugs and incompatibilities even as public beta downloads become available.
