Today, Apple released iOS 18.4, iPadOS 18.4, macOS 15.4, visionOS 2.4, tvOS 18.4, and watchOS 11.4. These releases represent an eclectic mix of new and updated features along with smaller changes scattered across each of the OSes.
One of the biggest changes is that the automatic message categorization feature added to iOS’ Mail app in December is now available on the iPad and Mac, although the Categories view can be switched back to List view if you prefer the old style. The updates to Mail on the Mac and iPad also include a digest view that combines multiple messages from one sender into a unified thread as well as sender contact photos.
Priority notifications have arrived on iOS, iPadOS, and macOS, too. The feature is designed to surface important alerts. In my experience, the feature works fairly well but has a more expansive definition of what a priority message is than I do.
