The Cupertino firm wants to have the version ready as soon as possible and is that the Christmas holidays are approaching so it would not be a good idea to have beta versions half-launched. In this sense, during the holidays Apple takes a break and therefore they want to have everything ready in terms of software to avoid problems. The developers already have in their hands this first beta version of macOS 11.1 Big Sur.
The beta versions of iOS and iPadOs have also been released a few hours ago by Apple and in all these new versions for developers the aim is to improve the stability and security of the system. We will see what day these new versions are officially released to all users but as we say, it is more than likely that they will arrive before the Christmas strike. Undoubtedly, the new version of macOS 11 Big Sur adds aesthetic, functional and system changes, so now It is time to adjust all this and detect the possible bugs that are found.
In any case, the improvements will continue to be implemented and polished in the following beta versions for developers and users registered in the public beta program, which by the way at the moment does not have the first version released but will be close to doing so. There are not too many changes but we already have more than in any previous version so all betas to correct errors are well received. If you are not a developer, it is best to stay out of them to avoid possible failures or incompatibility with any tool.
