14 DAY TRIAL // After releasing the second Beta of its upcoming iOS 11, macOS High Sierra 10.13, watchOS 4, and tvOS 11 operating systems to registered application developers, Apple now published the fourth Beta builds of iOS 10.3.3 and tvOS 10.2.2.
The iOS 10.3.3 Beta 4 (14G5053a) and tvOS 10.2.2 Beta 4 (14W5751b) development releases come about three days after the Cupertino company published the fourth Beta of the forthcoming macOS Sierra 10.12.6 operating system, while watchOS 3.2.3 remains at Beta 3 for now.
These are all small updates that include bug fixes and security improvements to enhance the stability, compatibility, and security of your iPhone, iPad, iPod touch, Mac, Apple Watch, and Apple TV devices, and you can test them all on your registered devices right now by download the builds from your Apple Developer account.
Now that Apple set released the Beta 2 builds of iOS 11, macOS 10.13, watchOS 4 and tvOS 11 to developers, it's time for the company to prepare for the Public Beta releases to allow the rest of the world, people that don't have a registered developer account to test the upcoming operating systems on their devices.
For that, Apple would need first to end the Public Beta program for iOS 10.3.3 and macOS Sierra 10.2.6 by releasing the final versions, which shouldn't be long, probably a week or two. iOS 10.3.3 Public Beta 4 is coming soon too, so make sure you update if you're running the Beta 3, as Apple already published the macOS 10.12.6 Public Beta 4 build.
