macOS Golden Gate 27 Security Update

What macOS Golden Gate 27 Fixes

macOS Golden Gate 27, released September 14, 2026, fixes 276 vulnerabilities in 119 parts of the system, according to Apple's security advisory.

Apple does not say that any of them were exploited before the fix. That makes macOS Golden Gate 27 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for macOS Golden Gate is macOS Golden Gate 27.2, from October 26, 2026, which includes these fixes.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.

Which Devices Get macOS Golden Gate 27

Apple lists macOS Golden Gate 27 for: 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), and Mac Pro with Apple silicon (2023).

The macOS Golden Gate 27 release page has its build numbers and release history.

How to Install macOS Golden Gate 27

On the Mac, open System Settings → General → Software Update. Macs that cannot run the newest macOS are offered the update for their own version there.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past macOS Golden Gate 27 there is nothing to do.
