macOS Sonoma 14.8.8 Security Update

What macOS Sonoma 14.8.8 Fixes

macOS Sonoma 14.8.8, released July 27, 2026, fixes 137 vulnerabilities in 71 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 Sonoma 14.8.8 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for macOS Sonoma is macOS Sonoma 14.8.9, from August 6, 2026, which includes these fixes.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 Sonoma 14.8.8

Apple lists macOS Sonoma 14.8.8 for: macOS Sonoma.

How to Install macOS Sonoma 14.8.8

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 Sonoma 14.8.8 there is nothing to do.
