14 DAY TRIAL // After announcing earlier today, November 28, 2016, the availability of the fourth Beta builds of the upcoming iOS 10.2, macOS Sierra 10.12.2, and watchOS 3.1.1 operating systems for registered developers, Apple seeded the Public Beta 4 build to the rest of the world.
It usually takes around 24 hours for Apple to seed the new Public Beta builds corresponding to the latest Beta update for its forthcoming iOS 10.2 and macOS Sierra 10.12.2 point releases, but considering the fact that there's been more than two weeks since Beta 3/Public Beta 3 were released, we believe the company was prepared this time to ship the new versions earlier than expected.
That being said, if you're using the Public Beta 3 release, we invite you to update your supported iOS 10.2 and macOS Sierra 10.12.2 devices to the Public Beta 4 build, which is available as we speak via the Mac App Store on macOS or the Over-the-Air (OTA) update system of iOS. Don't hesitate to read our previous report if you're curious to see the changes made in this version.
For those who are new to iOS and macOS public beta testing, we suggest you read 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. Also, we don't recommend using a Public Beta build on your device if you're looking for a stable, rock-solid iOS or macOS experience.
