Apple Releases Rapid Security Response Update for macOS Ventura 13.3 Beta

Apple today released a Rapid Security Response (RSR) update for the macOS Ventura 13.3 beta, with the update coming just a an hour after an RSR update for the iOS 16.4 beta.

Ventura Macs Feature Blue
macOS Rapid Security Response 13.3 (a) is applied to the Mac automatically upon restart.

This is the second RSR that Apple has released for a macOS Beta. The first RSR release did not add any new features, with Apple instead using the launch as a test to make sure it is functional before it is deployed for an actual security update. Today's update may also be launching in a test capacity, and it is unclear if it includes any actual security fixes.

Rapid Security Response is an iOS 16 and macOS Ventura feature released as part of those updates.

Last time RSR test was just a very minor toggle of Safari versions to show they could do it and then reverted it afterwards. It still requires admin permission and it reboots the Mac. The update was 175.3 MB.

Takes over 5 minutes to install..... At least they got with the program and got the patch out ASAP. The Windows would lives with update Tuesday every week.....
This is likely just a test, not a security patch.

I just got this. Makes Apple look bad that they seem unable to provide any fixes without having to reboot.

Welcome to Windows Vista.
How is that bad? Do you think anything that needs to occur low level before system is running similar to windows pre-fetch is accomplished without restarting the OS? That’s how’s a lot of malware runs on windows. :p
