Apple ships macOS Big Sur 11.3. You should update today

Along with the release of iOS 14.5, Apple has also updated macOS Big Sur to version 11.3. While the update brings a rash of important improvements, it also patches a huge security flaw and most Mac users should install the update today.

Why you should install the update immediately

macOS Big Sur 11.3 patches what has been called the ‘most impactful’ bug in Mac security discovered in recent history, as discovered by Cedric Owens. The flaw existed in the wild for months before Apple patched the problem, reports claim.

This nasty bug was able to bypass Apple’s macOS protections, including app notarization and Gatekeeper. Attackers then gained control of infected machines, including access to user data. All it took was the end use to open an infected file.

This is a really nasty bug, which is why Mac users should install the latest 11.3 patch immediately.

So, what about the good stuff? macOS Big Sur 11.3 adds support for AirTag, includes iPhone and iPad app improvements for Macs with M1, introduces separate skin tone variations for emoji with couples and adds more diverse voice options for Siri.
