A new version of macOS Big Sur was released yesterday, also known as macOS 11. This version corresponds to 11.2.1 and it was surprising for many users since the expected version was 11.3, which was and continues today in beta. The fact that Apple releases an intermediate version of a software can only mean one thing: major bug fixes . Indeed they exist and in this article we will tell you about them.
Bug fixes and security patches in macOS 11.2.1
Despite the general stability that macOS Big Sur has since it started in its first betas, the truth is that a series of errors have been appearing that have not been corrected in the different system updates since it officially arrived in the month of November. Among the errors corrected yesterday and as Apple itself comments, the solution to a problem in the MacBook Pro 2016 and 2017 with the batteries has been addressed, specifically one that prevented the battery from being charged continuously according to what moments . In fact, it was sometimes shown with a percentage of 1%, causing even many to consider the possibility of calibrating the MacBook battery.
But the most important of this update has been known thanks to another security document published by Apple in which it talks about the error CVE-2021-3156 that is related to a security flaw that allowed an attacker to obtain root access to a Mac , regardless of the model. In fact, this vulnerability could have been found last week and has finally been fixed in this version 11.2.1 of macOS. Apart from this security patch, others with less public relevance have also been added and other errors not as widespread as those discussed above have also been corrected with some MacBook Pros.
Should you update your Mac?
It is always advisable to have the computer updated to its latest version and it is precisely to guarantee your security against vulnerabilities such as the one mentioned above and others that arise in each version. In fact, many times errors are corrected that had not been announced or that even Apple does not detail with exactness, but that do not stop being less relevant. It is true that there is always a certain fear that something will stop working, especially if you work with third-party apps that usually take time to adapt to new versions of Mac software, so you should also take that into account.
If you decide to update, remember that the process is very simple. You just have to go to System Preferences> Software Update and you will find the macOS 11.2.1 version ready for download and subsequent installation. In the event that you have your device in an old version, it is possible that the update will appear in another place, specifically in the Mac App Store within the “Updates” tab. After the download process will be the same in both cases and will require an internet connection.
