Changes
Golden Gate adds intelligent features in Photos and Safari and child safety tools. Apple describes improvements to search, connectivity and system responsiveness. Siri AI and its capabilities are not equivalent to simply installing macOS 27; they have their own requirements and rollouts. Announced speed improvements are not independent tests in this entry. At launch, Siri AI began rolling out as a beta in English. Apple distinguished access on Mac in the European Union from the initial iOS/iPadOS restriction. China was excluded for these features. OS release is not the same as universal AI availability.
