Mac users can now download macOS Big Sur 11.3.1, a security-themed update to the version released a week ago. It closes security holes that Apple knows were exploited by hackers.

Monday was a busy day for updates. Apple also released watchOS 7.4.1 with one of the same security fixes. And it introduced iOS 14.5.1 and iPadOS 14.5.1 to take care of an App Tracking Transparency bug, and fix security bugs.

Apple is apparently preparing to release iPhone security updates separately from iOS updates with feature changes. The just-released fourth beta of iOS 14.5 gives users a new, separate toggle to choose whether to automatically install security updates.

However, at this point this feature doesn’t work quite as many might expect.

Several weeks after the release of macOS 10.13.4, today came a security update that patches some holes in this High Sierra version. This isn’t so critical that it has to be installed right now, but Apple says “This update is recommended for all macOS High Sierra users.”

There’re also security fixes for Safari 11.1, which was introduced recently too.

Apple issued a laundry list of updates on most of its operating systems to resolve what appears to be security soft spots.

Cupertino offered few specifics but the list includes macOS, tvOS, iOS, watch OS, Safari and iTunes and iCloud for Windows.
