Apple has released iOS 16.4.1a the first ever Security Response update for an iPhone and iPad! It’s a new type of software release that brings security improvements to your device, without an actual software update!
iOS 16.4.1a Security Update
Rapid security responses for iOS and iPadOS are installed automatically if you have the option enabled in Settings. However, we recommend you to do avoid automatic updates and keep things on manual. Here is how to proceed:
- 1. Open Settings and go for General -> Software Update.
- 2. iOS Security Response 16.4.1 (a) shows up similar to a regular software update.
- 3. Tap Download and Install.
- 4. Enter device passcode and be patient until the patch is downloaded, prepared and installed.
Tip: to toggle between automatic / manual Security Response Updates go for Settings -> General -> Software Update -> Automatic Updates and toggle the Security Responses & System Files option On or Off.
iOS 16.4.1a Security Features
Apple doesn’t provide a detailed update log about this software release. We’re informed that it could bring:
“improvements to the Safari web browser, the WebKit framework stack, or other critical system libraries. They may also be used to mitigate some security issues more quickly, such as issues that might have been exploited or reported to exist ‘in the wild.'”
More details can be found in Apple’s support document published here.
