14 DAY TRIAL // To everyone's surprise, Apple released today, April 17, 2017, the third Beta build of the upcoming iOS 10.3.2, macOS 10.12.5 Sierra, watchOS 3.2.2, and tvOS 10.2.1 operating systems.
The Beta 3 release comes exactly one week after the release of the second Betas of iOS 10.3.2, macOS 10.12.5, watchOS 3.2.2, and tvOS 10.2.1, and has been made available to both registered developers with a paid and active Apple Developer account, as well as public beta testers. However, Apple didn't reveal any of the changes made to these new Beta versions.
The new builds are tagged as 14F5080a for iOS 10.3.2 Beta 3, 16F60a for macOS 10.12.5 Beta 3, 14V5480a for watchOS 3.2.2 Beta 3, as well as 14W5578b for tvOS 10.2.1 Beta 3, and can be installed as we speak on your registered devices using the OTA update system of iOS, watchOS and tvOS, and the Sierra Developer Beta Access Utility tool for macOS.
How to jump into the iOS and macOS Public Beta bandwagon
While the release notes of iOS 10.3.2 Beta 3, macOS 10.12.5 Sierra Beta 3, watchOS 3.2.2 Beta 3, and tvOS 10.2.1 Beta 3 remain unchanged from the Beta 2 version, you can install these new Beta builds on your registered devices and try to discover yourself the new changes implemented by Apple's engineers.
If you've never joined the iOS 10 or macOS Sierra Public Beta programs, you can follow our in-depth "Here's How to Install iOS 10 Public Beta on Your iPhone, iPad, and iPod Touch" and "Here's How to Install macOS Sierra 10.12 Public Beta on Your Mac Right Now" tutorials to learn how to jump into the Public Beta bandwagon.
However, before installing anything, please try to keep in mind that these Beta builds won't offer you a stable iOS, macOS, watchOS, or tvOS experience, and you should make a full backup of your devices. We never recommend installing a Beta version of an OS to the faint of heart.
