Apple announces macOS 27 “Golden Gate,” the next major Mac operating system, during its WWDC 2026 keynote. Multiple outlets report the update centers on improvements to Siri, Apple Intelligence, and related features across the system. Wired and The Verge describe Siri being more accessible on the desktop, while Digital Trends and MacRumors add that the release includes a standalone Siri AI experience and upgrades to Apple Intelligence capabilities. 9to5Mac and MacRumors report changes to Spotlight, including a new “Search or Ask” style interface powered by a refreshed Siri. Several sources also describe UI refinements tied to Apple’s Liquid Glass design language, including adjustments to toolbars and sidebars; MacRumors says apps gain a unified toolbar and the sidebar can expand to the window edge, while The Verge adds that a global Liquid Glass opacity slider and tighter window corner radii are included. In addition, outlets agree Apple updates parental controls/child safety features across platforms. Slashdot separately reports that macOS Golden Gate ends support for Intel-based Macs and sets a cutoff such that Intel Macs will not be supported once the OS is released publicly, reported as in September or October.
