In iOS 16, Apple can deliver security updates to iPhones without having to update the entire operating system. Keep reading to learn how it works and how you can disable it if you prefer.

automatic security updates ios 16
In the past, some of Apple's most important point releases of its iOS mobile operating system have been linked to critical security updates that are designed to keep you and your private data safe and secure online.

Traditionally, one problem with these updates is that when a user opts to install them, the entire operating system must be updated and restarted.

In iOS 16, Rapid Security Response is an option that can let you avoid the rigmarole of all that, allowing you to get important security improvements to your devices even faster, and have them applied automatically between standard software updates.

When you update to iOS 16, Apple sets your device to install security updates automatically, but you can turn off the feature if you prefer. Here's how to do so.

  1. Launch the Settings app on your iPhone.
  2. Tap through to General -> Software Update.
    settings

  3. Tap Automatic Updates.
  4. Toggle off the switch next to Install Security Responses & System Files.
    settings

That's all there is to it. Note that depending on the critical nature of the update, some system files may continue to be installed automatically, even if this setting is turned off.
