Apple has released the fourth round of developer betas for its current generation of operating systems, with new builds of iOS 27.2, iPadOS 27.2, visionOS 27.2, watchOS 27.2, and macOS 27.2 now available for testing.
The fourth developer betas introduce more features ahead of the update's eventual public release. Typically the first major post-milestone update is a point-one version, but that is not the case this time. Because the iOS 27.1 build is designated for the iPhone Duo, that version is being skipped for the non-foldable iPhone models.
The new builds include iOS 27.2 beta 4 (24B5110a), iPadOS 27.2 beta 4 (24B5110a), macOS 27.2 beta 4 (26B5112a), watchOS 27.2 beta 4 (24S5112a), visionOS 27.2 beta 4 (24N5114a), and AirPods Firmware 9.1 beta 2 (9B5043a). Builds for tvOS 27.2 beta 4 and HomePod Software 27.2 Beta 4 have not yet arrived. Apple has also released RC builds for macOS 15.8.2 and macOS 26.7.2.
The fourth round follows the third release on October 5, the second on September 21, and the first on September 16. Earlier betas introduced a redesigned Health app, FaceTime dual capture support, expanded Siri AI localization, and Apple TV profiles from tvOS 26.2. A later build also showed signs of a new Auto Lock security feature that locks an iPhone if it is detected as stolen, though it is not yet accessible to testers.
AppleInsider advises readers to install beta software only on secondary hardware, since betas can contain bugs that put data at risk. Members of the public should use the public betas instead, and keep up-to-date backups in either case.
