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.
