As part of today’s announcements at WWDC 2022, Apple briefly mentioned a new addition to its security tools that will apply to iPhone, iPad, and Mac platforms called Rapid Security Response. It didn’t go into a lot of detail about what Rapid Security Response is, but Apple is promising to have important security updates that get to your devices even faster. Currently, iOS and macOS users get their security updates rolled in with full system patches, usually with .1 or .0.1 version numbers, which can take quite some time for users to download and install.

Now, Apple says its Rapid Security Response updates include important security improvements that “can be applied automatically between standard software updates.” MacRumors reports that for users who’ve installed the iOS 16 developer beta, there’s a new toggle under the Automatic Updates section of settings for “Install System and Data Files” to apply new security configuration and system data files. It says that “some updates may only take effect once you restart your iPhone,” which suggests that some won’t require a reboot.

That’s the case on macOS Ventura, where Apple’s breakdown of the new features coming in version 13.0 includes the Rapid Security Response, however on this platform “This isn’t a standard software update. These improvements can be applied automatically between normal updates — without a restart.” The Verge has contacted Apple for more information about the new updates, and with beta testers already running the new software, we should know more about how they work soon.
