Apple has released the second public beta of macOS 27, known as Golden Gate, providing non-developers with an updated look at the operating system ahead of its scheduled fall launch. This release, which carries the build number 26A5388g, aligns with the fourth developer beta seeded earlier in the week. The update focuses on performance stability and interface adjustments rather than a complete overhaul of the system architecture.
A primary focus of the Golden Gate release is the integration of a redesigned Siri, which now features personal context awareness and the ability to execute multi-step tasks across various applications. Users can access this new Siri experience via Spotlight using the Command + Space keyboard shortcut. The system also includes Visual Intelligence capabilities, allowing the assistant to analyze on-screen content to answer user queries or provide information.
Design changes in this beta address user feedback regarding the Liquid Glass aesthetic introduced in the previous macOS 26 Tahoe release. Apple has implemented a new slider for system-wide transparency control and adjusted the opacity of Liquid Glass elements to improve content diffusion. Additionally, the interface now features more consistent window corner radii, non-floating sidebars that extend edge-to-edge, and improved visual separation to help users identify active windows.
Under-the-hood improvements are intended to enhance system responsiveness, with early reports suggesting faster app launches and a smoother experience on older hardware. The search functionality within Spotlight, Mail, and Photos has been rebuilt with a new indexing engine to provide more relevant results. Furthermore, the update introduces AI-powered tools for writing and photo editing, alongside natural-language support for creating Shortcuts.
While the beta has been described as generally stable, users may still encounter occasional performance issues, memory management quirks in Safari, or inconsistencies with the Spaces feature. As with any pre-release software, Apple advises that testers should be prepared for potential bugs or app compatibility issues. Those interested in testing the software can enroll their devices through the official Apple beta website and enable updates within the System Settings menu.
