Apple released the second developer beta versions of iOS 27, macOS 27, iPadOS 27, watchOS 27, tvOS 27 and visionOS 27 on 2026-06-24.

Apple Issues Beta 4 for 26.5 OS Updates
Apple has released Beta 4 builds for iPadOS 26.5, watchOS 26.5, tvOS 26.5 and visionOS 26.5 to developers, with public betas expected soon. The 26.5 cycle emphasizes performance improvements while testing specific feature changes — including end-to-end encryption for Messages, Apple Maps search suggestions for nearby locations, and an App Store change to support annual subscriptions paid as monthly installments. Apple plans to officially present the update at WWDC 2026 in June, which will feature a Keynote and Platforms State of the Union. The report cites 9to5Mac and references prior Apple beta release notes for feature details.
Apple releases iOS 27 public beta; caution advised
Apple has opened the public beta for iOS 27, letting any registered user join the Apple Beta Software Program. To enroll, visit beta.apple.com, then install the beta on iPhone via Settings > General > Software Update and choose Beta Updates. iOS 27 adds modest features — including Threads support for RCS chats and a dedicated “Write with Siri” button — and includes performance improvements that Apple says can speed up older devices such as the iPhone 11. The publisher and Apple caution that betas may contain bugs: back up data (Time Machine recommended), install betas on non-production or secondary devices, and use a separate macOS partition for macOS betas. Developer betas preceded this release; the final public launch is expected around September–October 2026.
