Developers can now download the first betas of iOS 27.3, iPadOS 27.3 and macOS Golden Gate 27.3, a week after Apple shipped the 27.2 updates to everyone. The iOS beta is where Apple Intelligence testing starts in China. That includes Writing Tools, Live Translation, Genmoji and Alibaba’s Qwen in Siri, ahead of a public release with iOS 27.3 in December, according to Apple’s China Newsroom. Siri AI and the other new features from WWDC 2026 aren’t part of it.
