Apple Patches (almost) everything again. March 2026 edition.
Apple released the next version of its operating system, patching 85 different vulnerabilities across all of them. None of the vulnerabilities are currently being exploited. The last three macOS "generations" are covered, as are the last two versions of iOS/iPadOS. For tvOS, watchOS, and visionOS, only the current version received patches. This update also includes the recently released Background Security Improvements. Some older watchOS versions received updates, but these updates do not address any security issues.
