tvOS 18.4 Security Update

What tvOS 18.4 Fixes

tvOS 18.4, released March 31, 2025, fixes 47 vulnerabilities in 25 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 tvOS 18.4 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for tvOS 18 is tvOS 18.6, from July 29, 2025, which includes these fixes.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 tvOS 18.4

Apple lists tvOS 18.4 for: Apple TV HD and Apple TV 4K (all models).

How to Install tvOS 18.4

On the Apple TV, open Settings → System → Software Updates.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past tvOS 18.4 there is nothing to do.
