Overview
- Apple provided second developer betas for iOS 27, iPadOS 27, macOS Golden Gate, tvOS 27, visionOS 27 and HomePod Software 27, which arrived Monday and are available to registered developers via each device’s Settings app.
- iOS 27 centers on a rebuilt Siri AI that uses Apple Intelligence and new Foundation Models to give conversational answers, personal‑context awareness, on‑screen understanding, and a dedicated Siri app for past conversations.
- This beta wave emphasizes bug fixes, performance upgrades and UI refinements, including a Liquid Glass transparency slider, adjusted window corner radii, improved shadowing, faster app launches and snappier AirPlay and AirDrop behavior.
- visionOS 27 adds a placeable 3D Siri visualization and Visual Intelligence for Vision Pro that lets users ask about on‑screen windows or nearby physical objects, while Apple will not offer a public visionOS beta.
- Apple warned some Siri AI features will not initially ship in the European Union for regulatory reasons and advised installing developer betas only on secondary devices as public betas for most platforms are planned for July.
