Apple announced macOS 27 will be named macOS Golden Gate, continuing the company's tradition of naming OS versions after California landmarks. The update echoes the 2009 Snow Leopard approach, focusing on performance improvements and refining dozens of underlying technologies across all aspects of the operating system, from core functions to user-facing features like account creation.

Golden Gate introduces Liquid Glass design changes with unified toolbars and sidebars that expand to window edges. The OS finally delivers major Apple Intelligence upgrades including personal context and on-screen awareness for Siri. Spotlight gets a new "Search or Ask" interface powered by the revamped voice assistant, representing a significant enhancement to the system's search capabilities.

Apple is also revamping child safety features across its platforms with this release. The announcement precedes WWDC 2026, where Apple will likely demonstrate the operating system's capabilities and provide a more specific release date. This performance-focused approach could set a new standard for macOS development in the coming years as users await the full feature set.
