macOS 27 Golden Gate new features: 7 to try today

Apple released macOS 27 Golden Gate on Sept. 14, 2026, as a free update for eligible Macs, calling it a stability and performance release recommended for all macOS 27 users (Apple Support, yesterday). The headline macOS 27 Golden Gate new features center on Siri: Siri AI now lives inside Spotlight for conversational search, while a separate Siri AI app handles saved conversations synced through iCloud. Apple says Siri AI is rolling out gradually and that users should turn it on in Settings rather than assume it appears automatically (Apple Support, yesterday).

AppleInsider's launch-day testing calls Siri AI the release's best addition, but the same review flags unresolved bugs in the Phone app, Save dialogs, and Shortcuts' handling of Safari tab groups. Most eligible Mac owners can update today for everyday use. Anyone who depends on Mac-based calling, tab-group Shortcuts, or Save dialog menus should test those three workflows directly after installing, rather than assume the shipping build behaves the way the beta did.

What to check before you update

Apple's release notes don't include a device-by-device compatibility chart, only a general note that some features may not be available in every region or on every supported Mac (Apple Support). Checking Apple's compatibility documentation directly beats assuming Software Update alone confirms every feature, since a Mac can qualify for the Golden Gate update itself while still missing specific Apple Intelligence tools.

A pre-release report from July claimed Intel-based Macs are excluded from macOS 27 entirely, and that Golden Gate is the final version of macOS with full Rosetta 2 support for Intel-only apps. That reporting came out of beta-era coverage that predates Apple's final documentation, so it's worth treating as unconfirmed until Apple states it directly.

Apple also warns that usage limits may apply to several Apple Intelligence tools, including Siri AI, the intelligent photo editing tools, Image Playground, and the AFM 3 Cloud models that power Shortcuts (Apple Support). That matters most for anyone planning to lean on those tools heavily rather than use them occasionally.

Three workflows are worth testing right after installing. AppleInsider's launch-day testing found Mac-based Phone calls unreliable, with inconsistent audio routing and calls that sometimes never connect; Save dialog menus that don't always respond to clicks; and the long-standing bug preventing Shortcuts from opening Safari tab groups on Mac, still present in the shipping build. That reflects one reviewer's experience rather than a confirmed platform-wide failure rate, but all three take only a minute to check before relying on them for anything time-sensitive.

macOS 27 new features to try

1. Siri AI in Spotlight: conversational search with personal context

Apple has folded Siri and Spotlight into one interface, closing the gap between what used to be two separate search tools on the Mac (Six Colors, yesterday). Apple describes the result as more personal, capable, and conversational, able to draw on context from Messages, Mail, and Photos to help locate things across the system (Apple Support).

Results still depend on Apple's Spotlight index. Six Colors found that data living in apps not tied into that index, like Gmail used outside Apple Mail, doesn't surface at all, no matter how the question is phrased. Searching for a file or email known to sit inside an Apple-native app remains the more reliable way to judge how well this works at launch.

2. The dedicated Siri AI app: a persistent, cross-device chat window

Beyond Spotlight, Golden Gate adds a standalone Siri AI app that functions much like chatbots such as ChatGPT or Google Gemini, according to Tom's Guide, which has tested the software since its beta debut three months ago. It opens from the Dock, the menu bar, or Spotlight itself, and past conversations sync through iCloud, so a chat started on a Mac can pick up on an iPhone or iPad (Apple Support).

Tom's Guide also reports that a new "Ask Siri" entry often shows up at the top of right-click menus on files, folders, and apps, letting someone start a question about whatever's highlighted without opening Spotlight first. That "often" is doing some work: the option isn't guaranteed in every app, so its presence is worth confirming case by case.

3. Visual Intelligence: asking questions about what's onscreen

Visual Intelligence lets someone select a window on their screen and ask Siri AI questions about it, or trigger an action like adding an event to Calendar, using the shortcut Shift-Command-Space (Apple Support). Tom's Guide gives that calendar example directly: looking at a schedule surfaces an "add to calendar" button without switching apps.

The feature doesn't behave identically across devices carrying the same Siri AI name. AppleInsider's testing found Siri AI can manage Apple Music playlists on the Mac, something that still failed in the final iOS 27 beta, where the assistant would claim to add tracks but typically couldn't locate the playlist in question. Whether that gap persists on the stable release of iOS 27 hasn't been independently confirmed.

4. Describe a Shortcut: automation from plain language

Describe a Shortcut assembles the steps of a multi-step automation from a written description, such as automatically texting a partner an ETA when leaving work based on traffic (Apple Support). Typing or speaking a goal instead of manually chaining together individual actions lowers the barrier for anyone who's never built a Shortcut before; Tom's Guide says the process can feel like "vibe coding," even if it isn't quite that.

AppleInsider's testing found the underlying Apple Intelligence inconsistent, accurate in some attempts and wrong in others, and confirmed the Safari tab group bug noted above is still unresolved in Shortcuts. Apple's own warning about usage limits on cloud-based Shortcuts models applies directly here, so automation-heavy users shouldn't assume unlimited runs.

5. Photos' AI editing tools: Reframe, Extend, and Clean Up

Reframe (Spatial Reframing) lets users adjust a photo's angle, orientation, and framing after it's taken, with Apple Intelligence filling in the resulting gaps once the adjustment is made (Apple Support; Tom's Guide). Extend expands a photo beyond its original frame, and an upgraded Clean Up removes distractions with noticeably better results, even in cluttered scenes (Apple Support).

Spatial Reframing isn't exclusive to the Mac. Tom's Guide notes it also ships on iOS and iPadOS 27, which matters for anyone deciding whether this one tool alone justifies updating a Mac versus just using it on an iPhone or iPad.

6. Safari's Notify Me, automatic tab groups, and custom extensions

Notify Me keeps an eye on webpages for price drops or restocks and pings users when it's worth acting, while Safari now sorts open tabs into topic-based groups automatically, making related pages easier to track down (Apple Support). Apple has also added Describe an Extension, letting someone describe what they want in plain language and have Safari build it, such as a button for saving a favorite recipe.

These are narrower tools than the Siri changes above. Notify Me is built for a specific watch-and-alert use case rather than general browsing, and the tab grouping is aimed at people who keep large numbers of tabs open across topics.

7. Sidecar gains full iPad touchscreen support

Sidecar used to accept only Apple Pencil input when an iPad served as a second Mac display; Golden Gate adds direct touchscreen support instead (Six Colors, yesterday). Anyone running Sidecar as a regular second-screen setup can now tap the extended display directly instead of reaching for a Pencil for basic interaction, which matters most for quick app switching or scrolling.

Also worth knowing

Golden Gate adds a Liquid Glass slider that lets users dial interface translucency from ultra-clear to fully tinted, and Tom's Guide reports that complex backgrounds now render more diffused, improving text readability, with sharper icon edges to help windows stand out (Apple Support; Tom's Guide). Anyone who found the default look too busy has a direct control for it now instead of an all-or-nothing setting.

The Dock now flags apps that haven't fully quit but are still running in the background, with a contextual-menu note and a one-click option to shut down that processing (Six Colors, yesterday). It's a small troubleshooting addition for anyone chasing battery drain.

Golden Gate also expands parental controls: Ask to Browse now requires kids to request permission before opening any new website in Safari, Communication Safety broadens its protections, and Time Allowances and Schedules give parents more granular control over app access by category, age, and time of day (Apple Support). These apply mainly to family-managed Macs, so families already using Screen Time should check the settings individually rather than expect one new toggle to cover everything.

Not included in this release: Apple pulled its automatic compromised-password-changing feature from the shipping version after a Six Colors reviewer's own testing found roughly an 8% success rate during the beta (Six Colors, yesterday). Six Colors reports Apple intends to bring the feature back later this year, though that timeline comes from the reviewer's account of Apple's plans rather than a direct company statement, so it's worth watching Apple's own release notes before expecting it back on any fixed schedule.

Update now, or wait?

Apple documents Siri AI's Spotlight integration, the dedicated Siri AI app, Visual Intelligence, and the Photos editing tools in its release notes, and both Tom's Guide and AppleInsider have tested several of them directly. Tom's Guide, which has run the beta since three months ago, recommends updating as soon as a Mac supports it, though that's one outlet's take rather than a universal verdict, especially given the launch-day workflow problems reported elsewhere.

The more useful test is a personal one. Confirm the Mac supports Golden Gate through Apple's compatibility documentation, then check Settings and turn on Siri AI if it isn't already enabled. If Mac-based Phone calls, Safari tab group Shortcuts, or Save dialog menus matter to daily work, run each one immediately after installing rather than assume the update fixed problems reported at launch. Anyone who doesn't depend on those three workflows has little reason to wait.
