macOS 11.3 (Big Sur) is available, and in addition to new features, it also has a very important fix for a major vulnerability. Quickly learn why updating to macOS 11.3 is so important.
Why quickly update macOS 11.3
The latest update for macOS is now available for download. If you have already downloaded and installed these, then you are safe. Haven’t you done that yet? Then we recommend that you do so as soon as possible.
macOS 11.3 is not just an update with some extra functions. Somewhat more invisible to the average user, this update fixes a hugely dangerous vulnerability.
This vulnerability was discovered last March by security researcher Cedric Owens, and it ensures that all Apple’s protections are circumvented. Malware can be installed from a document or malicious website on any Mac that does not already have this update.
This vulnerability is already being actively exploited by hackers. In most cases it concerns a program that is being downloaded. If the user installs it, malware is spread on the computer. This malware completely evades Apple’s malware protection.
“This is probably the worst or potentially the most impactful bug for everyday macOS users,” says researcher Patrick Wardle. Vice.
More updates
macOS 11.3 has been available for download since Monday evening and is around 6GB in size. In addition to this important protection, macOS 11.3 also offers support for the new AirTag, among other things.
In addition, you can now also download iOS 14.5, with which you can use Face ID with a mouth mask if you wear an Apple Watch. There is also a new update for this Apple Watch available.
