macOS Sequoia 15 Security Update

What macOS Sequoia 15 Fixes

macOS Sequoia 15, released September 16, 2024, fixes 103 vulnerabilities in 63 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 Sequoia 15 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for macOS Sequoia is macOS Sequoia 15.8.2, from October 26, 2026, which includes these fixes.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 Sequoia 15

Apple lists macOS Sequoia 15 for: Mac Studio (2022 and later), iMac (2019 and later), Mac Pro (2019 and later), Mac mini (2018 and later), MacBook Air (2020 and later), MacBook Pro (2018 and later), and iMac Pro (2017 and later).

How to Install macOS Sequoia 15

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 Sequoia 15 there is nothing to do.
