Apple will allow you to take away the safety patches put in by iOS 16’s Fast Safety Response system, which may set up patches with out the necessity to totally replace your iPhone (and even with out having to restart it, in some circumstances). In keeping with a support document noticed by MacRumors, you possibly can take away a Fast Safety Response replace by going to Settings > Basic > About, then tapping on the iOS Model. From there, you’ll be offered with a “Take away Safety Replace” button.
The doc doesn’t give any examples of why you’d have to uninstall one of many patches, leaving your telephone open to the vulnerability it protects in opposition to. It’s simple to think about just a few particular circumstances the place the characteristic might be helpful, maybe if one messes up some particular work-related software program or administration instruments, as an example. In any other case, it’s a kind of options that most individuals ought to most likely by no means use until they’ve a really particular cause and totally perceive what they’re doing — type of like the brand new excessive Lockdown Mode, which is included to guard customers from “extremely subtle” focused cyberattacks.
Fast Safety Response is turned on by default, though you possibly can flip off the updates by going to Settings > Basic > Software program Replace > Automated Updates and toggling “Safety Responses and System Recordsdata.” If you happen to achieve this, you’ll have to attend for full iOS updates to get the safety patches. Once more, I’d personally advocate in opposition to turning the characteristic off until you’ve an express cause to, given what number of of Apple’s current updates have patched out fairly critical vulnerabilities.
The system can also be coming to macOS in Ventura, which hasn’t been formally launched but — thus far, Apple’s support documents for its desktop OS don’t point out whether or not you’ll be capable of roll again these updates as properly.
