macOS Tahoe 26.1 Security Update

What macOS Tahoe 26.1 Fixes

macOS Tahoe 26.1, released November 3, 2025, fixes 114 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 Tahoe 26.1 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for macOS Tahoe is macOS Tahoe 26.7.2, from October 26, 2026, which includes these fixes.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 Tahoe 26.1

Apple lists macOS Tahoe 26.1 for: macOS Tahoe.

How to Install macOS Tahoe 26.1

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 Tahoe 26.1 there is nothing to do.
