Apple has launched the first Rapid Security Response patches for iOS 16.4.1 and macOS 13.3.1 devices, with some users having issues installing them on their iPhones.
As the company describes in a recently published support document, RSR patches are small-sized updates that target the iPhone, iPad, and Mac platforms and patch security issues between major software updates.
Should you disable automatic updates or decline to install Rapid Security Responses when offered, your device will receive the security patches as part of a future software upgrade.
According to user reports [1, 2, 3, 4], the RSR update delivered today for iPhones also fails to install on some devices with "Unable to Verify Security Response" errors.
While today's Rapid Security Responses are rolling to all iOS and macOS users, Apple is yet to share what security improvements they bring.
The "Apple security updates" page, which usually lists the latest security updates, has no details on today's RSR patches, and Apple has not yet shared where they'll share this information.
