Users on the second iOS 16.4 beta have been given a new Rapid Security Response update as Apple tests the feature.
Apple intends to use Rapid Security Response updates in the future to quickly address discovered security vulnerabilities that are being actively exploited. This is the first Rapid Security Response update for iOS 16.4 beta testers.
The update can be found in the Settings app in the same place a normal update appears. This update is shown as iOS Security Response 16.4 (a).
Users that trigger the Security Response update are given the ability to revert to the previous iOS version during this test. Apple has tested this feature in previous betas.
