iOS 16.7.9 Security Update

What iOS 16.7.9 Fixes

iOS 16.7.9 and iPadOS 16.7.9, released July 29, 2024, fixes 27 vulnerabilities in 11 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 iOS 16.7.9 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for iOS 16 is iOS 16.7.16 and iPadOS 16.7.16, from May 11, 2026, which includes these fixes.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 iOS 16.7.9

Apple lists iOS 16.7.9 and iPadOS 16.7.9 for: iPhone 8, iPhone 8 Plus, iPhone X, iPad 5th generation, iPad Pro 9.7-inch, and iPad Pro 12.9-inch 1st generation.

How to Install iOS 16.7.9

On the iPhone, open Settings → General → Software Update. If more than one update is offered, the one with the higher version number is the current release; the other is for people who want to stay on the previous major version.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past iOS 16.7.9 there is nothing to do.
