What happened
Apple released macOS 27 Golden Gate on 14 September 2026 as a free update for Apple silicon Macs, alongside iOS 27 and other OS releases.
Apple released macOS 27 Golden Gate on 14 September 2026 as a free update for all compatible Macs, five days after the 26A428 release candidate on 9 September.
The headline is Siri AI — a rebuilt Siri powered by Apple Intelligence, integrated into Spotlight and as a dedicated Siri app. It can search personal context across messages, mail and photos and take action across apps.
Design gets subtle upgrades: a Liquid Glass slider for transparency, consistent window corner radii, edge-to-edge sidebars, refreshed app icons and redesigned traffic-light controls.
Compatibility is Apple silicon only: MacBook Neo, Air, Pro, iMac, mini, Studio and Pro. M1 and M2 get most features, but Siri voice customization and on-device Dictation need M3 or later with 12GB memory.
Who Gets What
Apple silicon only, but not all chips are equal. M1 and M2 Macs get the core Golden Gate experience, while newer silicon unlocks extra Siri smarts.
- All Apple silicon Macs: Siri AI, Liquid Glass, Visual Intelligence via Command-Shift-Space
- M3+ with 12GB+ required: Siri voice customization and improved on-device Dictation
- Intel Macs: no upgrade — macOS 26 Tahoe is final Intel release, last to support Rosetta
Timeline
- 9 Sep 2026 — Release candidate 26A428 seeded to developers
- 14 Sep 2026 — macOS 27 Golden Gate public release alongside iOS 27 and other OS updates
- October 2026 — Siri AI adds French, Japanese, Korean, Portuguese and Spanish
What To Do Next
Check Apple menu > About This Mac for chip and memory, then System Settings > General > Software Update to install. Back up first if you rely on Intel apps via Rosetta — this is the last macOS to support them.
Why it matters for me
Intel Mac owners stay on macOS 26 Tahoe with no upgrade path, while Apple silicon owners get Siri AI in Spotlight, Visual Intelligence and refined Liquid Glass.
Daily Life
Mac Owners
Apple silicon Mac owners get a free upgrade with Siri AI built into Spotlight and Visual Intelligence via Command-Shift-Space.
Money
Mac Owners
Intel Mac owners cannot upgrade — macOS 26 Tahoe is the last supported release, so staying current means buying Apple silicon hardware.
Work
Developers
Developers must ship Apple silicon-native apps — this is the last macOS to support Rosetta for Intel apps.
What to remember
macOS 27 is Apple silicon-only and Siri AI is the reason to update.
macOS 27 Golden Gate is out now — free, Apple silicon-only, with Siri AI built into Spotlight. Intel Macs are done.

10 claimsApple released macOS 27 Golden Gate as a free update on Monday, September 14, 2026, alongside iOS 27, iPadOS 27, watchOS 27, tvOS 27, and visionOS 27.
macOS 27 Golden Gate requires an Apple silicon Mac; Intel Macs are not supported, making macOS 26 Tahoe the last major release to support Intel-based Macs and Rosetta for Intel apps.
Siri AI is the headline feature — a revamped Siri powered by Apple Intelligence, integrated into Spotlight, with a dedicated Siri app, personal context search across messages/mail/photos, and the ability to take action across apps by asking.
Siri AI on Mac is shipping as a beta in English only, with French, Japanese, Korean, Portuguese and Spanish support coming in October. It is available in the EU on Mac when set to a supported language, unlike iOS 27 and iPadOS 27 which are not initially available in the EU.
Compatible Macs are: MacBook Neo (2026), MacBook Air with Apple silicon (2020 and later), MacBook Pro with Apple silicon (2020 and later), iMac with Apple silicon (2021 and later), Mac mini with Apple silicon (2020 and later), Mac Studio (2022 and later), Mac Pro with Apple silicon (2023).
Siri voice customization (pitch, speed, tone, accent) and the improved on-device Dictation model require a Mac with M3 or later and 12GB or more unified memory.
macOS 27 introduces a Liquid Glass slider to adjust transparency from ultra-clear to fully tinted, more consistent window corner radii, edge-to-edge sidebars, updated app icons, redesigned red/yellow/green window controls, and clearer active vs inactive window distinction.
Visual Intelligence arrives on Mac via Command-Shift-Space, letting users select a window of the screen and have Siri answer questions or take action on what's onscreen.
Apple released the macOS 27.0 release candidate (build 26A428) on September 9, 2026, preceding the public release five days later.
macOS 27 Golden Gate brings expanded parental controls to the Mac, including Ask to Browse (parent approval before new Safari sites) and Time Allowances by app category.
