Apple just made available to developers the fourth beta of macOS 10.15.4 t of tvOS 13.4 among others, because in this package it has also released the new versions for iOS and iPadOS. Apple is getting closer and closer to the stage of being able to launch this new beta version in a general version, that is, for all the public.
You know, if you are a developer, wait no more and download the new version to know what's new that you must implement for your applications or programs that you have in the Mac App Store.
Fourth beta, no news for the moment. Improvements and bug fixes
After having launched last February 26 the third beta of macOS 10.15.4 and tvOS 13.4, barely a week off the slope the American company launches what is the fourth beta. With this new version developers go one step further on the path of being able to adapt their programs and applications to what will be the new version of software for Apple TV and Mac in general.
As long as you are a developer, you can download this new version from the center or website that Apple has dedicated to this beta program. You can also install it by OTA installation, that is, requesting it through the appropriate device. In this case iPhone, iPad, Mac and TV.
It is too early to know what this fourth beta holds, but what is clear is that there will be bug fixes and improvements over the previous version.
As we always say in these cases, do not install this new beta on a main device, because of course, betas are used to test new elements that are not completely polished and can even generate irreparable errors. For this reason, it is better to always install it on a secondary device and thus avoid problems.
