One of the new features Apple introduced in iOS 16 is Rapid Security Response so that important security fixes don’t have to wait for a full iOS update before being released. Apple today released a Rapid Security Response update for iOS 16.2 Beta users to fix a security issue that exists in the system.
The Quick Security Response update for iOS 16.2(a) is pushed through the standard Software Update mechanism in the Settings app and is 96.8MB in size. The entire download and preparation process takes just a few minutes and requires a reboot for deployment once the update is complete.
Users can view information about this update in the “About” section of the Settings app after installing it, but naturally, you can also choose to remove it if you don’t feel the need.
Quick security responses will appear in future version updates for iOS 16, iPadOS 16.1, and macOS 13, by which Apple delivers security fixes more frequently. Such responses are included in any subsequent minor updates (not upgrades), and the content of the update on the Mac is displayed in the pre-boot volume (via a symbolic link in /System/ Cryptexes/).
Quick Security Response” involving the operating system requires a device reboot. A Quick Security Response involving the Safari browser requires the user to exit the App. OS update is delayed, the response will also be affected and delayed.
