Overview
- Apple seeded the fifth developer betas for iOS 27, iPadOS 27, macOS 27 Golden Gate, watchOS 27, tvOS 27 and visionOS 27, and the same builds reached public beta testers shortly after for several platforms.
- The builds expand Apple Intelligence’s system‑level Siri with a dedicated Siri app, Visual Intelligence tools and a ‘Write with Siri’ feature that can generate or edit text across apps.
- iOS 27 beta 5 enlarges Siri voice controls by adding Pace and Expressivity sliders for more voices but Apple limits those advanced, on‑device voice models to newer devices with about 12GB of RAM.
- The updates refine the Liquid Glass look with refreshed app icons, a new ‘Before Searching’ setting, Control Center tweaks and first‑launch splash screens to smooth the user experience.
- Platform‑specific changes include watchOS 27 dropping support for several older Watch models, visionOS 27 adding a 3D Siri orb and immersive panoramas, and Apple warning testers to use secondary devices as it stages region and hardware gating ahead of a likely September release.
