Shortly following the updates to iOS 16.4, iPadOS 16.4, and macOS Ventura 13.3, Apple has released iOS 15.7.4, iPadOS 15.7.4, macOS Monterey 12.6.4, and macOS Big Sur 11.7.5, all with important security fixes.
The company released iOS 16.4 and others on Monday with new actions in Shortcuts, more emojis, push notifications for web apps, and more features. But for older devices that can’t update to the latest operating system versions, there are iOS and iPadOS 15.7.4, macOS Big Sur 11.7.5, and macOS Monterey 12.6.4.
They contain essential fixes for security vulnerabilities across WebKit, Calendar, Camera, Accessibility, and other system components. Here are a few of them, although Apple hasn’t yet released security notes for the macOS updates.
