Apple today seeded the first public betas of iOS 27.3, iPadOS 27.3, macOS Golden Gate 27.3, tvOS 27.3, and watchOS 27.3, arriving two days after developer betas were released. iOS 27.3 introduces a Vertical Tabs layout for Safari and Adaptive Dark Mode, while Siri AI gains expanded capabilities across Apple apps. The redesigned Health app now features custom Insights and Longevity information. On Apple Watch Series 12 and Ultra 4, Audio Intelligence features Live Rewind and Siri Recap are available for testing. macOS Golden Gate 27.3 brings the same Safari updates and Live Activities support to Macs without a Dynamic Island.
The update cycle follows Apple's typical schedule, with a full public launch expected in December. Interested users can install the betas by signing up on Apple's beta testing website and selecting Software Update in the Settings app on each device.
