Apple has finally given macOS 27 a name, and it is a good one: macOS Golden Gate. Software chief Craig Federighi revealed it during the WWDC 2026 keynote, ending months of speculation that had centred on names like Emerald and Big Bear. But the name is only half the story. macOS Golden Gate is a landmark release for a bigger reason: it is the first version of macOS that runs exclusively on Apple silicon. The Intel Mac era is officially over.
Why macOS Golden Gate?
Apple has named every macOS release after a California landmark since 2013, working through Yosemite, Mojave, Big Sur, Sonoma, Sequoia and last year’s Tahoe. Golden Gate, after San Francisco’s most famous bridge, keeps that tradition rolling and is arguably one of the most recognisable names Apple has reached for yet.
The reveal also let Federighi run his now-traditional gag about Apple’s marketing team and their “unconventional methods” for naming releases. This year he joked that the team had piled into a microbus and gone “motoring northward,” leaving him with nothing but a note. With hindsight, that northward hint pointed straight at the Golden Gate. For the record, the pre-keynote betting had been split between macOS Emerald and macOS Big Bear. Both were wrong.
The End of the Intel Mac Era
The bigger headline is what Golden Gate leaves behind. Last year’s macOS Tahoe (macOS 26) was the final release to support Intel-based Macs, something Apple confirmed back at WWDC 2025. That makes macOS Golden Gate the first Mac operating system built solely for Apple silicon.
In plain terms: to install Golden Gate you need a Mac with an Apple silicon chip, meaning an M1 or later. If your Mac still has an Intel processor inside, this is where the road ends. You will stay on macOS Tahoe, which Apple will keep patching with security updates for a while yet, but you will not get Golden Gate or anything that comes after it. If you are not sure which camp your machine is in, we have a full breakdown of every Mac being dropped by macOS 27.
Why Cutting Intel Loose Actually Helps
There is a real upside to the clean break. With no Intel hardware left to support, Apple can build features purely for Apple silicon, lean fully on the Neural Engine for on-device Apple Intelligence, and stop dragging a decade of legacy compatibility along for the ride. The result should be a faster-moving, more tightly integrated Mac platform. The flip side, naturally, is an awkward day for anyone whose Intel Mac was still doing the job perfectly well.
What Is New in macOS Golden Gate?
Name and silicon aside, Golden Gate is a substantial update. The headline feature is the rebuilt, AI-powered Siri, a far more conversational assistant that shows up as an in-context helper inside your apps rather than a separate window. Around it sits a deep bench of Apple Intelligence additions, from systemwide proofreading and Smart Reply in your own writing style to a much-improved Image Playground, all wrapped in the broad “refinement year” polish Apple says it has applied across the whole system.
