Apple Releases Rapid Security Response Update for iOS 16.4 Beta Users

Apple today released a Rapid Security Response update that is available for those running the iOS 16.4 beta, marking the launch of the third RSR update since the feature was introduced in iOS 16.

The Rapid Security Response Update is designed to provide iOS 16.4 beta users with bug fixes without the need to install a full update, and this is likely a test update given the small file size.

iOS Security Response 16.4 (a) 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 16.4 users will see an updated version of iOS 16.4 (a), 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.

To me, this is really no different. If they still require a restart then it’s the exact same procedure with a different name. Download thing, agree to install thing, restart. No thanks.

A truly streamlined rapid update should work like updating apps through the App Store - I press a button and it does its thing in the background with zero disruption to my use of the device, no restart required, no password required, no nothing.
I mean, considering their infrequency, I wouldn’t let it bother you too much.

Well, this requires one simple reboot, which takes like 30 seconds.
A regular update requires a file install that’s anywhere from 200MB to 5+GB, a long preparing and verification process, and usually three reboots where the update actually indexes and installs.
That takes closer to 20 minutes to a half hour to even longer.

Rapidy fixing bugs. That's a new one.
They had to fix this bug to allow some bigger ones to get through for the public release.
