Apple has released on Wednesday the third beta builds of its upcoming iOS 11.2.5, macOS 10.13.3 High Sierra, tvOS 11.2.5, and watchOS 4.2.2 operating systems for supported devices.

Coming about two and a half weeks after the second beta builds, today’s iOS 11.2.5 beta 3 (15D5049a), macOS 10.13.3 beta 3 (17D29a), tvOS 11.2.5 beta 3 (15K5544a), and watchOS 4.2.2 beta 3 (15S5536a) builds are now available for registered developers through the Apple Developer website.

There isn’t much information available about the bug fixes and improvements that Apple implemented in the third beta update to its upcoming software updates for all supported iPhone, iPad, iPod touch, Macs, Apple TV, and Apple Watch devices. Most probably, they improve the security and stability of these devices.

All we know right now is what Apple published in the release notes of each of these beta versions, which is not much, at least for macOS 10.13.3 beta 3 and watchOS 4.2.2 beta 3. For iOS 11.2.5 beta 3, there’s a fix for an ARKit issue and two Xcode workarounds, while tvOS 11.2.5 beta 3 addresses a system time bug where the time was incorrectly set after a power interruption to an Apple TV.

Public Beta 3 builds coming soon too

As these dev beta builds are currently only available to registered application developers with a paid and active Apple Developer subscription, public beta testers will be able to install the iOS 11.2.5 beta 3, macOS 10.13.3 beta 3, and tvOS 11.2.5 beta 3 updates in the next 24 hours.

While we don’t encourage users to install beta software, if you feel adventurous enough, don’t hesitate to check out our straightforward tutorials on how to install the iOS 11, macOS High Sierra, and tvOS 11 Public Betas (herehere and here). But before you jump on the Public beta bandwagon, do make a backup of your device in case anything wrong happens.

We expect Apple to release the final iOS 11.2.5, macOS High Sierra 10.13.3, tvOS 11.2.5, and watchOS 4.2.2 software updates sometimes at the end of the month or in early February. We’re looking forward to seeing if Apple will implement the new battery monitoring features in iOS or not, which were promised to customers last week.
