Apple unveiled macOS 27, codenamed Golden Gate, at its 2026 developer conference, highlighting a suite of AI-driven enhancements that span the operating system.
A dedicated Siri app will store conversation history in a single location and synchronize it across Macs, iPhones, and iPads via iCloud, allowing users to continue interactions seamlessly on different devices.
Siri’s personal context awareness will draw on messages, email, notes, photos, and files, enabling the assistant to locate specific information, retrieve previously saved content, and surface relevant details from a user’s own data.
The new Siri AI will access up-to-date web information, delivering answers on virtually any topic and assisting with research, interview preparation, and rapid learning.
App actions and automation expand Siri’s reach into Messages, Music, Reminders and other apps, permitting natural‑language commands to edit messages, manage playlists, create reminders and perform other tasks without manual navigation.
Integration with Spotlight Search lets users type queries directly into the search bar and receive AI‑generated responses, eliminating the need to launch a separate assistant app or switch to a browser.
Visual Intelligence arrives on macOS, allowing users to select on‑screen content—such as images, documents, or text—and ask Siri questions about the selected material.
Integrated writing tools give Siri the ability to generate new text, rewrite drafts, summarize content, and adapt tone, wording and punctuation to match a user’s typical communication style.
System‑wide dictation receives a major upgrade, automatically inserting punctuation, capitalization and formatting while offering higher speech‑recognition accuracy.
Customizable Siri voices will let users choose a voice and adjust pace and expressiveness, though the feature requires newer Apple silicon hardware.
Siri AI will enter beta later this year, initially supporting English and requiring Apple Intelligence‑compatible devices.
Apple Intelligence also powers system‑wide proofreading, delivering automatic spelling and grammar suggestions throughout macOS.
Intelligent file and folder naming will propose names based on content, streamlining organization across the system.
Privacy remains a focus: on‑device processing is prioritized, with Private Cloud Compute handling additional workloads without storing personal data, and the architecture remains open to independent security verification.
Safari gains AI‑driven capabilities, including automatic grouping of related tabs into topics, a “Notify Me” feature that monitors webpages for changes such as price drops or restocks, and the ability to generate custom extensions from plain‑language descriptions.
Messages and Mail receive deeper AI integration, offering Smart Reply suggestions that reflect a user’s writing style, one‑tap actions to create reminders or notes from conversations, photo suggestions based on chat context, and an improved search ranking system that surfaces the most relevant email results first.
The Photos app introduces AI editing tools: spatial reframing to intelligently recompose images, an Extend tool that expands photos beyond their original borders, and an enhanced Clean Up feature capable of removing larger unwanted objects.
UI refinements include more pronounced Liquid Glass effects, higher contrast for better readability, consistent refraction across windows and controls, updated toolbars, edge‑to‑edge sidebars, refreshed menu bar icons, background bars behind window controls, uniform rounded corners, and customizable Liquid Glass appearance ranging from ultra‑clear to fully tinted.
Performance improvements cover faster AirDrop transfers, accelerated network file browsing, quicker Safari start‑page loading, and support for 5K ultrawide displays at 120 Hz, with more reliable monitor arrangement memory.
macOS 27 supports the MacBook Neo, MacBook Air and Pro (Apple silicon 2020 onward), iMac (2021 onward), Mac mini (2020 onward), Mac Studio (2022 onward) and Mac Pro (2023 onward). Certain Siri AI features require an M3 chip with at least 12 GB of unified memory.
The developer beta is scheduled for June 8 2026, the public beta for July 13 2026, and the final release is expected in September 2026, likely around September 14.
Apple advises most users to wait for the public beta, while developers may opt into the developer program; a complete backup is recommended before installing any beta version.
Intel‑based Macs will not receive macOS 27, and support for Rosetta 2 ends, marking the final stage of Apple’s transition away from Intel architecture.
