Apple released the sixth public betas of iOS 27, iPadOS 27, tvOS 27, and macOS Golden Gate, one week after the fifth public betas and a few hours after the eighth developer betas. This compressed cadence, moving to weekly developer beta drops in August, shows that Apple is in the final polish phase before the September release alongside the new iPhone lineup.
iOS 27 supports iPhone 11 and later, as well as iPhone SE 2 and newer models. IPadOS 27 runs on iPad Air 2 and later, iPad Pro, iPad (5th generation and later), and iPad mini 4 and later. TvOS 27 works on Apple TV 4K and Apple TV HD. MacOS Golden Gate runs on Mac models from 2017 onward, with M-series Macs receiving full optimization. Siri AI and other Apple Intelligence features require newer hardware across all platforms, limiting advanced functionality to more recent devices. The broader compatibility window means the core experience of each platform works on devices from 2017 to 2019 onward.
Across iOS 27, iPadOS 27, tvOS 27, and macOS Golden Gate, the headline feature remains Siri AI, a rebuilt assistant powered by the next generation of Apple Intelligence and new Apple Foundation Models. The assistant incorporates general world knowledge alongside personal data from apps like Messages and Mail, with onscreen awareness capabilities that let Siri understand what’s displayed on screen and act accordingly.
Other features in testing include an improved Liquid Glass look with a slider for customizing transparency, and multiple performance improvements designed to make each platform feel faster across the board, including on older devices. These optimizations matter historically; older devices like the iPhone 11 and iPad Air 2 receive support, and Apple has faced criticism when OS updates degrade performance on previous-generation hardware.
Apple’s pivot away from major new features echoes the company’s effort to avoid repeating iOS 26’s early stability problems. That release launched with significant bugs affecting battery life, notification delivery, and system responsiveness, forcing multiple point updates within the first month. The accelerated weekly beta schedule through August demonstrates how seriously Apple is treating the refinement phase this time around across all four platforms, with no notable new features appearing in the latest developer betas.
Release candidate versions are expected to rollout either next Monday, or after Apple’s September 9 iPhone event.
