Apple is testing a new Background Security Improvements system in iOS 26.3(a) betas that delivers reversible, background security patches for components like Safari and WebKit, replacing the rarely used Rapid Security Response. The system supports automatic or manual installation, promises faster delivery of critical fixes across iOS, iPadOS, and macOS, and allows problematic updates to be removed, aiming to improve security response times while minimizing disruption.
