At the same time as the iOS 4 developer and public beta 10, Apple has released the also beta 4 of all the operating systems that they presented in the last WWDC, that is, tvOS 10.0, watchOS 3.0, and macOS Sierra 10.12. Both the fourth beta of iOS 10 as well as the betas for the fourth generation Apple TV, for Mac computers and for the Apple Watch are available only for developers, at least at the moment in which I began to write these lines.
The three releases have occurred just two weeks after the launch of beta 3 of each of the operating systems and they are already available from the Apple Software Center. We remember that the most difficult beta to install of the 3 is tvOS, although watchOS is not as easy to install as iOS and macOS.
Beta 4 of tvOS 10, macOS Sierra, and watchOS 3
Although we can take some surprises, something that, in fact, usually happens in the first releases of all Apple operating systems, we still cannot talk about any outstanding novelty. What we can say is that the new versions will include bug fixes and performance improvements, as well as security improvements.
We do not recommend the installation of any software in the testing phase, but if you decide to install any of the three versions mentioned above, do not hesitate to comment saying what you have discovered. We will write a post about any interesting news that we find both in iOS 10 beta 4 (which I think has somewhat different emoji ...), as in tvOS 10 beta 4, macOS Sierra beta 4 and watchOS 3 beta 4.
