Apple has announced that the latest version of its macOS, called macOS 27 Golden Gate, will be released on September 14. This date coincides with the launches of the new iOS 27 and iPadOS 27 updates. The final version, known as the Release Candidate (RC), has been sent to testers after the eighth beta version. Registered users can download the RC through their Mac's System Settings, under General and then Software Update, provided they have enabled the Beta options and are using a free Apple Developer account. macOS Golden Gate brings several visual and usability changes. The interface now includes new themed wallpapers and screen savers, while the Liquid Glass design has been tweaked to improve readability. A new cursor feature allows users to adjust transparency levels, and work on shadows aims to make the active window more prominent. The overall design moves toward a more minimalist look, with applications featuring uniform toolbars and sidebars that stretch from one edge of the screen to the other. Apple is reverting to fixed-radius corners for windows, moving away from the variable angles introduced in the previous macOS version. The menu bar now displays fewer icons, and some gestures from iOS, such as swiping down to refresh content, have been integrated into system apps, hinting at potential future touchscreen Macs. One of the most notable updates is the introduction of Siri AI, a more advanced voice assistant that integrates directly into the Spotlight search engine through a new query interface. Siri AI uses general knowledge, on-screen context, and personal data from apps like Messages, Mail, and Photos to provide more accurate responses. A dedicated Siri app allows users to write and review past conversations via iCloud, and on newer Macs, users can customize the assistant's voice. Siri AI will be available at launch for users in the European Union, including France, but will initially only support the English language. It also features Visual Intelligence (activated with Command-Shift-Space), allowing Siri to analyze a screen area for actions like adding calendar events. The Write with Siri feature helps users generate or refine text. Apple has also rolled out AI-powered features across its usual applications. In Photos, users can now adjust perspective or framing after taking a photo (Spatial Reframing) or expand an image's field (Extend). The Clean Up tool has improved algorithms for removing objects from complex scenes, and raw file support now includes the RAW 9 standard. Safari now automatically groups tabs by theme and supports the swipe-down refresh gesture. A new "Notify Me" feature allows users to track changes on web pages, such as price drops or product restocking. Safari also allows users to create custom extensions from natural language instructions. The Shortcuts app now includes a tool that builds action sequences from text descriptions. In the Passwords app, users can automatically update weak passwords, while the Image Playground app has been redesigned to generate more realistic images. Apple Podcasts now supports video content, and iPhone screen mirroring has seen performance improvements. macOS 27 Golden Gate introduces new family management features, including the Ask to Browse function, which requires parental approval before accessing new websites in Safari. The Communication Safety suite expands its protections, while Time Allowances and scheduling options help manage screen time based on a child's age and weekly schedule. Technically, Apple reports faster search performance in Spotlight and Mail, as well as quicker file transfers via AirDrop and local networks. The update is compatible with Macs equipped with Apple silicon chips. This includes models like the MacBook Neo (2026), MacBook Air and Pro (2020 and later), iMac (2021 and later), Mac mini (2020 and later), Mac Studio (2022 and later), and Mac Pro (2023). However, advanced features like Siri AI require at least an M3 chip and 12 GB of RAM. Apple notes that certain AI-based features, including Siri AI, image editing tools, and cloud models, may be subject to regional restrictions and usage limits. The company also warns that installing the update might impact a Mac’s performance and battery life.
