The fifth round of developer betas for Apple’s upcoming fall releases is now available, covering iOS 27, iPadOS 27, macOS 27 Golden Gate, tvOS 27, watchOS 27, and visionOS 27.

Apple released the first builds on June 8, followed by the second on June 22 and June 23 for watchOS, and the third on July 6. The fourth round dropped on July 20, and the new builds result in 24A5408d for iOS and iPadOS, 26A5406e for macOS, and comparable identifiers for the other platforms.

Early releases added the long‑awaited Liquid Glass UI, a full Siri overhaul, child‑protective features, Apple TV integration in the Home app, and new Wallet insights. The third beta introduced visual tweaks and more Siri AI customisation on newer iPhone models.

Because the operating system is still in active development, Apple warns that beta software can be buggy or harmful. Developers are advised to use spare hardware, while the general public should wait for public betas or the final release later in 2026.
