Apple has started seeding the fourth beta of the upcoming iOS 9.3.3 update to developers and public beta testers just a week after seeding the third beta for the same update. Along with the iOS update, Apple also seeded the fourth beta versions for OS X 10.11.6 and tvOS 9.2.2.
The latest iOS update, like its predecessors, is a minor one and comes with build 13G33 designed to fix performance and get rid of a few bugs. There are no major UI changes listed as of now. The update can be downloaded over-the-air using the beta configuration profile or through the Apple Developer Center.
The OS X update comes with build no 15G24b whereas the tvOS update comes with build no 13Y824. These updates for Macbooks and the Apple TV are also minor updates with some bug fixes and stability improvements.
This will most likely be the last set of betas to be seeded by the company before it releases the public OTA versions for these updates. Apple has avoided any major UI changes in these updates owing to the recent release of the iOS 10 at the WWDC conference.
iPhone, iPad and iPod touch devices were seeded the iOS 10 beta 1 update shortly after the WWDC announcement but a public beta version is yet to be announced. Meanwhile developers are eagerly awaiting the beta 2 version for the iOS 10. The final iOS 10 version will only be released at Apple's September event where it is also expected to unveil the iPhone 7.
