Apple releases the fourth developer beta updates for multiple upcoming operating systems, continuing its developer beta program. Developers can download the new builds now for iPadOS 27 and tvOS 27, along with additional platforms including iOS 27, macOS 27, and watchOS 27. This fourth round follows earlier beta releases: AppleInsider reports that the third developer betas arrived on July 6, while the second beta releases occurred on June 22 for most of the operating systems. For watchOS 27 specifically, AppleInsider notes that related developer betas landed on June 23 and June 25 before the current fourth builds. The reports describe these releases as in-progress testing versions available through Apple’s developer program. Both outlets focus on availability to developers and the version numbering of the betas, without detailing new features or changes included in the fourth builds.
