macOS 27 Golden Gate Debuts with Siri AI, Liquid Glass refinements, and Safari upgrades

Apple rolls out macOS 27 Golden Gate with a refreshed Liquid Glass UI, a dedicated Siri AI app and broader Apple Intelligence on-device models, plus Safari upgrades (Notify Me, Describe an Extension, tab grouping, pull-to-refresh), Shortcuts enhancements, and new Photos tools, all while boosting performance and reliability; iPhone Mirroring gains resizable windows but remains EU-limited, Rosetta support ends with this release, and some features require newer Apple silicon (A18 Pro, M1+) and regulatory clearance.
