Apple has officially released macOS 27, titled Golden Gate, bringing a significant focus on system refinement, performance optimizations, and the integration of advanced machine learning across the operating system. While the update maintains the core aesthetic of recent iterations, it introduces deep functional shifts, particularly within the way users interact with their data and applications.
The update is centered on the rollout of a new AI-powered experience for Siri, overhauled system utilities, and a suite of “intelligence” features that aim to automate routine tasks. As with previous major releases, availability of specific features depends on language, region, and hardware specifications.
Siri AI and the New Search Interface
The most prominent change in macOS 27 is the integration of a rewritten Siri experience. Apple has replaced the standalone, floating Siri window with a “Search or Ask” bar, accessed via the familiar Command-Space shortcut. This interface now acts as the primary gateway for interacting with the operating system’s intelligence. Users can conduct standard file and application searches while simultaneously engaging in natural language conversations with Siri.
The system is designed to perform complex actions across various native applications, such as extracting information from emails to populate calendar events or finding specific images based on descriptive queries. For those who prefer alternative models, Apple allows users to switch the default assistant in the “Ask…” menu. However, it is important to note that conversational context does not carry over when shifting between providers.
Advanced Photos Editing and Management
The Photos application has received substantial upgrades in Golden Gate, primarily driven by new generative models. The updated “Clean Up” tool provides higher-quality background reconstruction, moving beyond simple object removal to more complex environment synthesis. Users can now choose between “Fast,” “High Quality,” and “Auto” modes when processing images.
Furthermore, Photos introduces two new editing utilities: “Reframe” and “Extend.” Reframe allows for the adjustment of camera perspectives in compatible images, while Extend utilizes generative AI to fill in empty space when changing the composition or aspect ratio of a photo. For power users, the app now supports manual star ratings and custom keywords, which can be toggled on in the application’s General settings. These metadata features provide a more robust way to filter and organize massive photo libraries.
Safari and Browser Productivity
Apple’s Safari browser sees improvements in both organization and automation. The Start Page now features a “Recently Viewed” section, which syncs active browsing topics across all signed-in devices. For users who juggle numerous open pages, a new automatic grouping feature sorts tabs by topic, isolating unrelated research sessions.
A noteworthy addition is the “Notify Me” feature, which allows Safari to monitor a webpage for specific changes, such as a price drop or an item returning to stock. Additionally, users can now generate custom browser extensions using natural language prompts. By simply describing the desired functionality, such as creating a button to save recipes, Safari can generate the necessary logic without requiring the user to write code.
System Interface and Accessibility Updates
macOS 27 introduces a new “Liquid Glass” transparency slider within the Appearance settings, providing granular control over the clarity of window elements. This complements a broader design shift that includes standardized toolbars and edge-to-edge sidebars, which are intended to make active windows easier to distinguish.
For accessibility, a new “Show Borders” option adds visual emphasis to interface elements, helping users identify buttons and panels that might otherwise blend into the background. Productivity is also enhanced by the ability to add “Extra-Large Portrait” widgets to the desktop, allowing for more prominent placement of weather, reminders, and Home controls.
Connectivity and Cross-Device Features
The integration between Mac and other Apple devices has been further refined. iPhone Mirroring windows are now fully resizable, and the feature supports the playback of protected video streams. Furthermore, the Sidecar feature has been updated to allow direct touch interaction with the Mac interface on a connected iPad, enabling users to scroll and select elements using their fingers.
The update also includes a significant shift for Shared Albums. While they now support full-resolution media, the previous unlimited storage benefit for the first 5,000 items has been removed; any media added to shared albums now counts toward the user’s total iCloud storage quota.
Hardware and Compatibility Requirements
It is essential to note that Golden Gate represents a major transition in the ecosystem. The operating system is exclusive to Macs running on Apple silicon; Intel-based machines are no longer supported. Furthermore, this is the final major macOS version that will include general-purpose Rosetta support for running older Intel-based applications. Apple has signaled that native support for these legacy apps will cease in the subsequent major update, with the exception of specific gaming titles, marking a definitive end to the transition period for the Mac platform.
