Today Apple released the beta version for developers of macOS High Sierra 10.13.5 and simultaneously released the public beta versions of tvOS 11.4 and iOS 11.4. These beta versions add much the same thing that is added in the developer beta versions and Apple makes them available to registered users.
In this case the version of tvOS 11.4 beta 2 adds like the first version a featured novelty, AirPlay 2. In this sense, the typical improvements in the system, bug fixes and solutions to the problems reported in the first public beta, launched earlier this month, are added.
AirPlay 2 is the main novelty
Despite being the only novelty that changes in tvOS 11.4, the truth is that the AirPlay 2 function is not entirely polished and you have to work a little more on it. In fact was implemented in tvOS 11.3 and had to be retired Due to operating problems, now it seems that everything is going better but it must be finished polishing.
Again we can see in these versions that there are no major aesthetic or functionality changes, this is something that Apple has already warned would happen and this is happening. Actually the improvements implemented in these beta are related to tvOS performance, something that they have been doing for a long time and it seems to work since there are few faults that we find in the operation of the Apple TV.
It should be remembered that the registration to be able installing the public beta versions is completely free And no developer account is required, yes, we are exposed to the same risks that the installation of beta versions entails on our Apple TV.
