Apple released the fifth beta of iOS and MacOS Sierra developers for a while. This is specifically iOS 10.3 and macOS Sierra 10.12. IOS 10.3.3 is released a week after the release of the fourth beta release and more than a month after the iOS 10.3.2 release that fixes minor bugs. And macOS Sierra 10.12.6 comes two weeks after the release of the fourth beta release and more than a month after the release of macOS Sierra 10.12.5.
The version is getting more mature and more polished, for which we would not be surprised that a final version of this iOS 10.3.3 is released, which has gone quite unnoticed in terms of the new features implemented. In part we were all waiting for iOS 11 and its pubic beta and this version has been left in the background. The public beta of this iOS 11 has brought to some users some extra headache for wanting to try the new version and it is that it seems that Apple has somewhat complicated the return to the previous version.
The fifth beta of iOS 10.3.3 can be downloaded by all developers who have a developer profile on their device. Updates are done by default in Settings → General → Software Updates.
The fifth beta version of macOS Sierra 10.12.6 can be downloaded by all developers who have a developer utility on their Mac. Updates are then done via the Mac App Store via the Update tab.
iOS 10.3. 3 could be one of the latest updates to iOS 10. Apple is likely to start thinking about the emerging iOS 11, which will be released in the final version in autumn. IOS 11 was introduced at WWDC on 5 June. In the following months, the final version will be debugged.
