Apple rolls out security update for iOS 18.3.1, iPadOS 18.3.1, macOS Sequoia 15.3.1

Apple has released updates with security fixes for its operating systems, bringing them up to iOS 18.3.1, iPadOS 18.3.1, watchOS 11.3.1, macOS Sequoia 15.3.1, and visionOS 2.3.1.

While the main attention is on the major updates to Apple's operating systems, it also introduces minor point releases from time to time. On Monday, Apple did just that.

As a point release, there is relatively little expectation of major feature changes, but they tend to include performance improvements. Indeed, the notes for the iOS 18.3.1 update says it includes "important bug fixes and security updates," which Apple claims is "recommended for all users."

The security notes for the release says there is a fix for an issue that "may have been exploited in an extremely sophisticated attack against specific targeted individuals."

Point releases are also commonly used by Apple to add support for unreleased hardware. Current rumors say that an iPhone SE update is expected to arrive soon.

The updates for iOS, iPadOS, watchOS, macOS Sequoia, and visionOS arrive at a time when Apple is anticipated to bring out a new wave of developer betas. This would include iOS 18.4, iPadOS 18.4, and macOS 15.4, among others.

The build number for iOS 18.3.1 and iPadOS 18.3.1 is 22D72. The macOS Sequoia 15.3.1 release build number is 24D70, the visionOS 2.3.1 update is build 22N900, and watchOS 11.3.1 is build 22S560.

Alongside the updates for the newer operating systems, Apple has also released an update for the previous generation of iPadOS. The update for iPadOS 17.7.5 is build 21H420.

iPhone and iPad owners can manually update their devices by opening the Settings app and selecting General, followed by Software Update. If the update is available, tap Update Now.
