Just over two weeks after the most recent releases, Apple has introduced additional updates: iOS 18.4.1, iPadOS 18.4.1, macOS 15.4.1, tvOS 18.4.1, and visionOS 2.4.1. These updates contain fixes for two major vulnerabilities that are known to be actively exploited. Apple advises installing these updates on compatible devices to ensure optimal security.
