On September 14, 2026, Apple released six major operating system updates, collectively called "Platform 27," which included iOS 27, macOS Golden Gate, and others, all featuring a redesigned Siri powered by Google's Gemini and Apple's new Foundation Models. iOS 27 introduces a more conversational Siri that can understand context, along with new features like Liquid Glass design refinements and enhanced photo editing tools, but requires newer hardware to utilize the AI capabilities. macOS Golden Gate marks the last version to support Rosetta, while also offering visual design updates and system-wide Siri integration for tasks like text rewriting. Additionally, security patches were released for older versions, and while Siri AI is available in English, other languages will roll out later, with certain regions excluded due to regulatory issues

Apple Platform 27 Release: iOS 27, macOS Golden Gate and Siri AI

Apple shipped six major operating system updates in a single "Platform 27" wave on September 14, 2026, including iOS 27, iPadOS 27, macOS Golden Gate, watchOS 27, visionOS 27, and tvOS 27. The unifying feature across every platform is a redesigned Siri powered by Google's Gemini and Apple's new Foundation Models, adding context-aware responses, a dedicated Siri app, and deeper system integration. For users not ready to jump to a major version, Apple also released security-only patches in iOS 26.7, macOS Tahoe 26.7, and macOS Sequoia 15.8. Caveats include iOS 27 fixing more than 100 vulnerabilities, macOS Golden Gate being the final Mac release to support Rosetta, and tvOS 27 shipping without the new Siri AI.
