Apple's now on the fourth round of developer betas for this generation, with new builds of iOS 27.2, iPadOS 27.2, visionOS 27.2, watchOS 27.2, and macOS 27.2 out for testing.

The fourth developer betas for iOS 27.2, iPadOS 27.2, macOS 27.2 Golden Gate, watchOS 27.2 and visionOS 27.,2 have arrived, testing out more features before the update's eventual release to the public.

Typically, the first major post-milestone update is a point-one version, which isn't the case this time. As the iOS 27.1 build is designated to be used with the iPhone Duo, that version is being skipped for the non-foldable iPhone models.

The fourth 27.2 builds are:

  • iOS 27.2 beta 4 is 24B5110a, replacing 24B5099f
  • iPadOS 27.2 beta 4 is 24B5110a, replacing 24B5099f
  • macOS 27.2 beta 4 is 26B5112a, replacing 26B5101f
  • watchOS 27.2 beta 4 is 24S5112a, replacing 24S5101f
  • visionOS 27.2 beta 4 is 24N5114a, replacing 24N5103f
  • AirPods Firmware 9.1 beta 2 9s 9B5043a

New builds for tvOS 27.2 beta 4 and HomePod Software 27.2 Beta 4 have yet to arrive. This post will be updated if they do in the near future.

Apple has also released RC builds for other operating systems:

  • macOS 15.8.2. RC 2 is build 24H225
  • macOS 26.7.2 RC 2 is build 25G325

The fourth round follows after the third, which Apple shared on October 5. The second appeared on September 21, and the first round landed on September 16.

The first round introduced a few changes to iOS 27.2, including a redesigned Health app, which works alongside the Apple Watch Ultra 4 and Apple Watch Series 12.

FaceTime gained dual capture support, Siri AI added localization for multiple languages, and Apple TV profiles from tvOS 26.2 came over to the iPhone.

The second build had indications of a new AutoLock security feature, which locks down an iPhone if it is detected to have been snatched or otherwise stolen from the owner. The feature isn't accessible to testers, but it was spotted as running in the background in a non-functional manner.

AppleInsider warns readers trying out beta software should do so on secondary, spare hardware instead of their mission-critical or daily driver devices. There is always a risk of buggy, broken, or other potentially harmful elements in beta software, which can be a risk to your data.

Members of the public should seek out the public betas instead of the developer versions as safer alternatives. In either case, it is also advisable to keep up-to-date backups on hand.
