Apple has started providing small security updates to iOS, iPadOS and macOS devices known as Background Security Improvements. These updates offer minor system updates between larger software updates, delivering lightweight security releases for components like the Safari browser and WebKit framework. They download in the background and require a restart to complete. Applying these updates is faster than typical software updates, with the inaugural update patching WebKit. These updates are available for devices running iOS 26.1, iPadOS 26.1 and macOS 26.1, with details accessible in the Privacy & Security section of the Settings menu.
