macOS 27
What we know about macOS 27 — the WWDC 2026 reveal, the likely compatible Macs, and whether the beta is worth installing.
macOS 27 "Golden Gate" is Apple's 2026 Mac operating system, announced at the WWDC 2026 keynote on June 8. It's the first macOS to run only on Apple Silicon, ending Intel support entirely. Headline changes: a Gemini-powered Siri, a refined Liquid Glass interface, and a rebuilt Spotlight. Two developer betas are out (June 8 and June 22), with the stable release expected in September 2026.
macOS 27 is in developer beta — and it drops Intel Macs.
Apple announced macOS 27 Golden Gate at WWDC 2026 on June 8. It runs only on Apple Silicon Macs (M1 and newer); four 2019-2020 Intel Macs that ran macOS 26 Tahoe lose support. The developer beta is out now, with the stable release expected in September 2026. Don't install an early beta on a Mac you depend on. Everything here reflects Apple's confirmed keynote announcements.
Check compatibility, then wait for the public beta or stable release →In short.
Confirmed coverage. Apple announced macOS 27 "Golden Gate" at WWDC 2026. It is the first Apple Silicon-only macOS, ending Intel support. Headline changes: a redesigned Siri built on a Google Gemini model, a refined Liquid Glass interface with adjustable transparency, and a rebuilt Spotlight with natural-language search.
The headline question is hardware. macOS 27 needs an Apple Silicon Mac (M1 or later); Intel Macs can't install it. Rosetta 2 still runs your older Intel apps through macOS 27 — the app cutoff doesn't arrive until macOS 28 in 2027.
Apple Silicon Macs (M1 or later): Golden Gate is a substantial upgrade, worth installing at the September release. Intel Macs: macOS 26 Tahoe is your ceiling, with security updates continuing for about two more years.
Should you install the beta?
Our verdict for the macOS 27 Golden Gate developer beta.
- Apple Silicon (M1 or later)… WaitmacOS 27 supports your Mac. The developer beta is out now, but it's early — test on a secondary Mac, or wait for the public beta and the September stable release on your main machine.
- Supported Intel Macs (four 2019-2020 models)× SkipmacOS 27 drops Intel entirely, so these Macs can't install it. macOS 26 Tahoe is your final version, with security updates for roughly two more years.
- Older Intel Macs× SkipNot supported. These dropped off the list before Golden Gate. Stay on your current macOS.

Quick answers
The questions about macOS 27 we get asked most.
When was macOS 27 announced?
Apple announced macOS 27 Golden Gate at the WWDC 2026 keynote on June 8, 2026, and seeded the developer beta the same day. The stable release is expected in September 2026.
Will macOS 27 run on my Mac?
Only if it has Apple Silicon (an M1 chip or newer). macOS 27 drops Intel entirely. Four 2019-2020 Intel Macs that could run macOS 26 Tahoe lose support: the 2019 16-inch MacBook Pro, 2020 13-inch MacBook Pro, 2020 27-inch iMac, and 2019 Mac Pro.
Will my older Intel apps still work on macOS 27?
Yes. macOS 27 keeps full Rosetta 2, so Intel-compiled apps still run on Apple Silicon Macs through 2026. The real cutoff for Intel apps is macOS 28 in fall 2027, not macOS 27.
