Visual Intelligence lets users interact with on-screen content via Command-Shift-Spacebar. Safari gains tab grouping, page-change notifications, and natural language extension creation. The update also features refined Liquid Glass interface design, expanded parental controls for web browsing and app usage, and performance improvements to search, AirDrop, and network browsing. Some AI features may have regional or usage limitations.
