Apple Releases Another Rapid Security Response Update for iOS 16.2 Beta Users

Apple today released a Rapid Security Response update that is available for those running the iOS 16.2 beta, marking the launch of the second RSR update since the feature was released in iOS 16.

The Rapid Security Response Update is designed to provide iOS 16.2 beta users with bug fixes without the need to install a full update. The initial RSR release for iOS 16.2 beta users was a test with no actual bug fixes, and given the size of this update, it too is likely for testing the RSR system.

iOS Security Response 16.2 (b) is available through the standard Software Update mechanism in the Settings app, but is a quick update, requiring just a couple of minutes to download the update and then a quick restart for the install process.

Once the Rapid Security Response update is installed, iOS 16.2 users will see an updated version of iOS 16.2 (b), and tapping on the version in the About section of Settings will display information about the installed iOS version and the Rapid Security Response update. Those who want to disable Rapid Security Response updates can do so by following our how to.

Very small for a security update
Isn’t that the point?

Would be nice if Apple released a changelog worth a damn to go along with it.
Why, if it’s a security response it could publicise a security vulnerability that would still be an exploit for unpatched devices.

These releases have been to test the functionality of applying patches in such a way.

How big should a security update be then? It could be just one bit or byte that needs patching.
