Apple rolls out continuous background security updates for iPhone, iPad and Mac
Apple has begun rolling out Background Security Improvements that run in the background between major OS updates, delivering lightweight security releases for WebKit, Safari, Mail and App Store across iPhone, iPad and Mac. The feature is supported on iOS 26.1, iPadOS 26.1 and macOS 26.1 and is enabled by default with an option to disable in Settings; the first rollout began March 17, 2026, with additional background updates expected between releases.
