Apple released macOS Golden Gate with Siri AI as its centerpiece, available for Macs with M1 or later chips. The update includes performance improvements, enhanced Liquid Glass transparency controls, redesigned UI elements like toolbars and sidebars, and Visual Intelligence features that let Siri understand on-screen content. Siri now functions as a chatbot accessible via Spotlight, can access personal information and complete tasks, and includes system-wide writing assistance.
