On June 22, Apple released the second beta version of macOS Golden Gate (macOS 27) for developers. This update comes about two weeks after the first developer beta was launched. Developers can enter the update page through "System Settings > General > Software Update". After turning on the "Beta Update" option and logging in with a free developer account, they can download and install the new version of the system.

According to reports, macOS Golden Gate has made many adjustments and optimizations in the interface design. The Liquid Glass effect in the system increases the opacity to enhance the readability of text and content, while a new slider is added to control the transparency level, and the shadow effect has been adjusted to make it easier for users to distinguish the currently active window. The system application toolbar style is more unified, the sidebar adopts a welt design, the window rounded corners are narrowed, and the number of icons in the menu bar has also been reduced to improve overall visual consistency.
In the new system, Siri has been upgraded to "Siri AI" and transformed into an intelligent assistant similar to a chatbot. Siri AI combines general world knowledge, user personal data, and awareness of screen content to answer questions and find information. The portal is integrated within Spotlight, and users can interact with it directly through the new "Search or Ask" interface. Additionally, a standalone Siri app is available where users can have conversations with Siri and view history. On newer Mac devices, users can also set a custom voice for Siri, including speaking speed and delivery style.
macOS Golden Gate also brings Visual Intelligence to the Mac platform, allowing Siri to understand images or interface content on the screen and answer relevant questions based on this. The new "Write with Siri" function can help users generate text or suggest modifications to existing text, providing intelligent assistance for daily writing and office scenarios.
In terms of system applications, a number of artificial intelligence-based photo editing tools have been added to the photo application to facilitate users to quickly optimize or adjust images. Safari browser adds a new AI tab organization function, which can automatically classify and manage tabs to improve the multi-tab browsing experience. In the password application, there is a new option to use AI to automatically update weak passwords to enhance account security. In addition, the Image Playground application has also been reworked and now supports the generation of more realistic photorealistic images, providing more possibilities for creation and image generation.
For more detailed information about the new features of macOS Golden Gate, Apple-related content can be found in the accompanying system overview. The current version is still only open to developers. Apple plans to launch a public beta version of macOS Golden Gate in July, when ordinary users with eligible devices will also have the opportunity to experience this new generation of systems in advance.
