Apple released the third developer betas for its upcoming operating systems, including iOS 27, macOS 27, watchOS 27, tvOS 27, visionOS 27, and iPadOS 27. This release continues the testing cycle ahead of the public launch expected in the fall.

The second developer betas for most of these platforms arrived on June 22, with watchOS 27 beta 2 following on June 23 and June 25. The current third builds replace the previous versions, with specific build numbers provided for each OS, such as iOS 27 beta 3 (24A5380h).

These early betas are intended for developers to familiarize themselves with changes, which have previously included updates to Siri, child-protective features, and minor app adjustments. AppleInsider advises users to install beta software on non-essential devices due to the potential for bugs and instability, recommending that consumers wait for public betas or the final release.

The ongoing beta process suggests Apple is focused on refining the user experience for its 2026 product lineup. Developers will continue to receive updates, with the expectation that major issues will be resolved before the final public rollout.
