Apple today released a Rapid Security Response update that is available for those running the iOS 16.4 beta, marking the launch of the fourth RSR update since the feature was introduced in iOS 16.

The Rapid Security Response Update is designed to provide iOS 16.4 beta users with bug fixes without the need to install a full update, and this is likely a test update given the small file size.

iOS Security Response 16.4 (b) is available through the standard Software Update mechanism in the Settings app, but is a quick update, requiring just a couple of minutes to download the update and then a quick restart for the install process.

Once the Rapid Security Response update is installed, iOS 16.4 users will see an updated version of iOS 16.4 (b), and tapping on the version in the About section of Settings will display information about the installed iOS version and the Rapid Security Response update. Those who want to disable Rapid Security Response updates can do so by following our how to.

Update: Apple has also released a second rapid security response update for macOS 13.3 Ventura beta users.

The second RSR was a repeat of the exact same test of a new updating method. Slightly modify Safari and then revert it back the same as MacOS 13.3 beta 2. They had to do this before coming out with a beta 3 which is expected in a day or two.

MacOS 13.3 beta 2 (b)
  • Version 16.4 (18615.1.24)
  • System Firmware Version: 8422.100.640.505.1 (M1 based Macs)
  • Darwin Kernel Version 22.4.0: Wed Feb 22 22:16:19 PST 2023; root:xnu-8796.100.763.505.1~1/RELEASE_ARM64_T8103 arm64
MacOS 13.3 beta 2 (a)
  • Safari Version 16.4 (18615.1.24.110.1)

Build number for MacOS 13.3 beta 2 (b) is 22E7752300g (up from 22E7752300f if you previously had MacOS 13.3 beta 2 (a)).

Irregardless of the builds you back to the beta 2 baseline before the mod and unmod. :D

Doesn't fix the issues of rare crashes between Safari and Mail, something that 13.3 beta 2 added vs 13.3 beta 1.

I wish there was a way to apply these quick updates without a restart. I suppose it’s not feasible to update the OS while it’s running, unless it’s a very specific component that isn’t needed all the time to make the OS function.

From my understanding, in actual practice the nature of the update will indeed dictate whether a restart is necessary.

Good to see Apple working towards decoupling security updates from full OS updates.

Apple has always done incremental OS updates when an urgent security risk needs to be remediated across multiple OS's. They don't stall until the next OS update comes out if it is something serious. Even if the RSR is used for something minor as far as system changes it still requires system prep that takes several minutes and reboot for MacOS as an example. iOS/IPadOS the same.

Yes there have examples in the past where Apple has delayed patching because of the nature of what happened. Something requiring more extensive examination.
 

Windows Vista, sorry macOS Ventura, should never have been released.​

I've never seen a macOS version this buggy and sluggish. Also iPadOS is full of bugs.
Apple must be working hard to reach Microsofts level of incompetence.

I wonder why this makes the news. They're probably just testing the mechanism again in the Beta channel.

This fixes nothing. It is meant to test the update mechanism itself.

Wait, Are you saying that potential issue of less battery life is not a security issue and won't be addressed in a security update?!?! I mean surely Apple can see how lower battery life could be a security risk for folks in the woods or desert with no power, no battery packs, no cars, etc available. :)

I am not saying that at all. I am saying that THIS particular update doesn’t address any issues in the OS as it is meant to test the new update mechanism of the OS itself.

This is a small update of 3.8MB that does nothing more than change the version number of Safari.

In real life, this update mechanism will be used to fix all sorts of issues, but as they are pushed to users they will most likely be exclusively used to address zero-day vulnerabilities.

I've found Ventura to be the most stable OS release I've had in recent memory ( admittedly did jump from Catalina to it), but just goes to show how much experience varies

In this context I think security means software security ie risk of data breach etc not safety of life. So fixing a 0day will be done as a security update, while fixing a battery drain that might drain a betery whil hiking as you said, would probably not be. Unless ofc the batery drain really is some process slipping under the radar and sending data to unwanted places, thus keeping the radio from going to sleep.

Butt I'm no apple insider so I have no idea what they classify as what

Ok clearly I missed the mark being humorous. This post was purely in jest. I understand what these new security updates are going to be for as well as these recent ones are simply testing the process. The other person that posted asking if battery drain would be fixed is where I was going. Oh well I wont quit my day job as comedy is not my best work :)
