Just yesterday it was the developers who had in their possession the beta versions of macOS Mojave, iOS 6, tvOS 12 and watchOS 12. A few hours ago the Cupertino company officially released the beta versions for users registered in the program. macOS Mojave, iOS 12 and tvOS 12 public betas.
These versions are still the best option to install today if you want to try the betas and they are also completely free and do not require more than a real Apple ID for installation. Today these versions aThey add the same or practically the same as the beta versions for developers.
The installation is very simple if we already have the previous versions on our Mac, so we have to go to the System Preferences in the case of macOS Mojave to install the new version. This version also adds the improvements in the native tool to pass information from Windows to Mac, so we have the same news at the beginning. And it is that the versions for developers always add a few more things so that they can fiddle with the system.
In any case, the new versions for registered users in the public beta program are already available. As we always advise make a backup before installing a beta, or better yet, not install it in any partition with relevant information from our day to day, as we may lose information or the program that we use daily to perform some important task may not be operational. It is best to install any beta on external hard drives, with sufficient speed or USB memory with high speed and capacity, to test macOS Mojave with a minimum of performance.
