Just Updated to macOS 27 Golden Gate Try These 15 New Features First

Apple released macOS 27 Golden Gate to the public on September 14, 2026, after a developer beta that started in June. It's a refinement release built around a new AI-powered Siri and small but useful changes across Apple's built-in apps. If you just installed it and aren't sure where to look first, here are 15 features worth trying right away.

What's New in macOS 27 Golden Gate?

Apple says macOS 27 Golden Gate focuses on refining features introduced in the previous release based on user feedback, rather than reworking the whole system. Before you dig into the new features, there's one compatibility detail worth knowing.

Golden Gate drops support for all Intel-based Macs, including the 2019 Mac Pro, the 16-inch MacBook Pro from 2019, the four-Thunderbolt-3-port 13-inch MacBook Pro from 2020, and the 2020 iMac, ending support for x86-64 processors. It's also the last major release to include general-purpose Rosetta support for Intel-only apps on Apple Silicon Macs, except for certain older games. With that out of the way, here's what to explore first.

A. Siri AI and Smart Search Features

1. Ask Siri AI Directly From Spotlight

Spotlight now doubles as a "Search or Ask" bar. Pressing Command-Space lets you hold a conversation with Siri, find relevant information in apps like Mail and Photos, and take actions in supported apps. It's the quickest way to test the new assistant without opening a dedicated app.

2. Try Visual Intelligence on Anything Onscreen

Visual Intelligence has come to the Mac. Pressing Shift-Command-Space lets you select something onscreen, then ask Siri to explain it, translate text, or search for similar images. It can also act on what it recognizes, like pulling details from an event flyer straight into the calendar.

3. Write Siri Draft or Edit Your Text

Writing With Siri can generate a draft from a description, give feedback on existing text, or make a requested edit, such as shortening a paragraph or changing its tone. It works in nearly any text field, and Apple says it can adapt to your usual writing style in Mail and Messages.

B. Safari Upgrades

4. Turn On Automatic Tab Organization

Safari can now automatically group open tabs by topic while keeping unrelated browsing sessions separate. You turn it on in Safari's Settings, under the Tabs section, by choosing "Organize Tabs: Automatically Create Topics." It's a small setting that makes a real difference if you tend to keep dozens of tabs open.

5. Set Up Notify Me for Page Changes

Notify Me lets Safari watch a webpage for a specific change, such as a product restock or price drop, and alert you when it happens, with daily, weekly, or monthly monitoring options. It's useful for tracking limited-stock items or waiting for a fare drop without checking manually.

C. Productivity Apps That Got Smarter

6. Create Calendar Events With Plain Language

The calendar can now create or edit an event from a plain-language description, adjusting the details when you tweak the wording rather than requiring every field to be edited separately. Typing "lunch with the team Friday" and later editing it to "coffee chat" updates the event automatically.

7. Draw Natively in Notes

Notes now has a native drawing tool on the Mac, so you no longer need a linked iPhone or iPad to sketch. It includes Pen, Monoline, Marker, Pencil, Crayon, Fountain Pen, Reed, and Watercolor tools. This closes a long-standing gap for anyone who uses Notes for quick visual notes on a Mac only.

8. Add Reminders Using Natural Language

Reminders can fill in details such as a date, time, or location when you type a natural-language request, instead of making you set each field individually. It's a small time saver for anyone who adds reminders throughout the day.

9. Build a Shortcut by Describing It

Shortcuts can now build automation from a plain-language description, assembling a sequence of actions across apps that you can test, edit, or refine with another description. New triggers also let a shortcut run when you take a screenshot or receive a notification, alongside existing triggers like time of day and location.

D. Photos and Mail Improvements

10. Test the Rebuilt Clean Up Tool

Clean Up now uses new AI models and does a better job reconstructing backgrounds when removing objects, with Fast, High Quality, and Auto modes available, though usage limits may apply. It handles more complex backgrounds than the version in previous releases.

11. Try the Extend and Reframe Editing Tools

Extend lets you expand the borders around a photo using generative AI to fill in missing areas, changing the composition, while Reframe uses AI and spatial image data to shift the apparent camera angle of a compatible photo. Both are worth testing on photos taken with a recent iPhone.

12. Smarter Mail Search and Smart Replies

Mail search now ranks messages by relevance rather than matching words and recency, so an order confirmation can surface ahead of promotional emails from the same sender. Smart Replies also reflect your usual writing style and tone, so a quick reply sounds more like something you would have written yourself.

E. System, Files, and Display

13. Adjust the New Liquid Glass Transparency Slider

System Settings now has a slider under Appearance that lets you adjust Liquid Glass from ultra-clear to fully tinted, alongside improved contrast, window shadows, and standardized toolbars. It's worth a look if the translucent interface elements in the previous release felt hard to read.

14. Let Apple Intelligence Suggest File and Folder Names

In Finder, TextEdit, and other Apple apps, Apple Intelligence can suggest a name for a file or folder based on its contents, which helps when a saved item's original name doesn't explain what's inside it.

15. Explore the Redesigned Weather App

Weather has a more orderly layout with more room for hourly and 10-day forecasts, separate views for current conditions, precipitation, and wind, and a new Highlights section for notable weather ahead, though Highlights are currently limited to U.S. English.

Final Verdict

macOS 27 Golden Gate isn't a dramatic visual overhaul. It's a refinement release built around Siri AI, small but genuinely useful changes across built-in apps, and interface polish carried over from the Liquid Glass design introduced in Tahoe. For most Apple Silicon Mac owners, it's a safe update worth installing, especially if Safari, Photos, Mail, or productivity apps are part of your daily routine.

Intel Mac owners are left out of this release entirely, and if you still rely on Intel-only apps through Rosetta, it's a good time to plan an alternative, since Apple says those apps will stop working in the next major release, apart from certain older games.
