Apple has recently rolled out a Rapid Security Response (RSR) update to beta testers of macOS 13.3 and iOS 16.4 platforms. The RSR update is designed to address any discovered security vulnerabilities as quickly as possible.
While the 16.4(a) version is the first RSR update released for macOS 13.3 and iOS 16.4 beta platforms, it is the second RSR update Apple has released for a macOS Beta. The company released the first RSR update earlier but did not add any new features. Instead, Apple used the update as a test to ensure its functionality before its deployment for an actual security update.
Apple’s software notes say the update “provides important security fixes.” The company recommends that all beta testers install it. If you’re a beta tester and want to learn more about the update’s content, you can access an online support document by clicking on the link provided.
One significant difference between beta RSR updates and public ones is that beta testers can revert to a previous version of macOS or iOS. In contrast, public updates may only be reversed if the last version is not signed off. Additionally, macOS Rapid Security Response 13.3(a) is applied to the Mac automatically upon restart.
It still needs to be determined if today’s RSR update includes any security fixes or if it is launching in a test capacity. The RSR is an essential feature released in the macOS Ventura and iOS 16 updates.
If you are a beta tester of macOS 13.3 or iOS 16.4, you can download the RSR update by accessing your device’s settings on iOS and going into General for macOS Ventura. Stay protected and update your devices now.
