Apple has just made iOS 9.3.3 beta 4 and OS X El Capitan 10.11.6 beta 4 seeds available to both developers registered on Apple Developer Program, and testers registered on Apple Public Beta Program. Alongside the latest iOS 9.3.3 and OS X 10.11.6 betas, tvOS 9.2.2 beta 4 for Apple TV 4 has also been released. These latest seeds of iOS 9.3.3, tvOS 9.2.2 and OS X El Capitan 10.11.6 come only a week after beta 3 seed of the said platforms were made available for download on compatible iOS, Apple TV and Mac devices. Here we take a look at what exactly is new, if any, in each of these latest builds, one by one.

iOS 9.3.3 Beta 4

The fourth beta of iOS 9.3.3 comes one week after the release of the third pre-release seed, meaning that iOS 9.3.3 has now been on testing with internal and external testers for more than a month. As you would expect from a point update of this nature, iOS 9.3.3 contains under-the-hood improvements which focus on stability and trying to provide a better user-experience for iPhone, iPad and iPod touch users interacting with the platform. Those internal improvements mean that there are no outward-facing changes to write home about.

Developers and public beta testers are able to install the latest beta as an over-the-air (OTA) update from Settings > General > Software Update if a pre-release version of iOS is already installed on the device. If not, iOS 9.3.3 beta 4 IPSW file or an Apple Configuration Profile for iOS 9.3.3 can be grabbed from either developer.apple.com or beta.apple.com.

tvOS 9.2.2 Beta 4

And the progression of tvOS 9.2.2 continues. Developers are able to continue testing the latest version of tvOS to ensure compatibility of apps, as well as providing valuable feedback to Apple about bugs and security issues that may exist. Like the current public version of tvOS, version 9.2.2 doesn’t contain any notable user-facing changes that Apple TV owners are able to interact with via the Siri Remote or a connected Bluetooth device. Instead, as is usually the case for these point releases, Apple has chosen to focus on eradicating bugs and making important security changes and improvements to provide an overall improved user-experience.

As is always the case, developers are able to download the latest beta of tvOS from developer.apple.com, and then using iTunes and a USB-C cable to restore the firmware. If a previous beta is already installed on the Apple TV, then the fourth and latest beta should be accessible directly on the device as an over-the-air (OTA) update.

OS X El Capitan 10.11.6 Beta 4

The fourth beta of OS X 10.11.6 could very well go down as one of the latest betas to be offered to developers and public testers before the the name change comes into play and macOS Sierra is released to the public. This fourth beta of Apple’s desktop platform comes just a week after the third pre-release seed of OS X El Capitan 10.11.6, meaning that the software has been in testing for more than a month now. Like previous betas, this fourth offering doesn’t contain any notable outward changes, instead choosing to focus on stability improvements and bug fixes.

According to Apple, this update improves the stability, compatibility, and security of Macs running the platform. Developers and public testers are able to download and install the latest beta update from the Mac App Store.
