Repeated internet failures after installing macOS 13.6.5

The only Full Versions of Ventura goes back to Venture 13.6.3

Maybe if you have SafetyNet enabled on the CCC there might still be a full version of Ventura 13.5 ?

softwareupdate --list-full-installers

Finding available software

Software Update found the following full installers:

* Title: macOS Ventura, Version: 13.6.5, Size: 11916934KiB, Build: 22G621, Deferred: NO

* Title: macOS Ventura, Version: 13.6.4, Size: 11912664KiB, Build: 22G513, Deferred: NO

13.6.5 broke the internet on 10'ish of the 250 computers we just updated. If you're backed up you should erase the disk in disk utility before you reinstall the OS. We spent an hour or so trying to fix the problem but never found a solution. The internet does work in safe boot.

We're having the same issue. We use JAMF for MDM. Doesn't seem like any apple silicon macs are affected, just our 2017 Intels. Very frustrating as we install a ton of software on these macs so wiping them and re-imaging isn't ideal.

Our macs get proper IP configuration, but no internet access, however the internet works in safe mode. The logs show theast activity on the macs was the 13.6.5 update.

Thats what we're seeing. Again, not a lot, like 4%. But enough to notice. Gave up trying to figure it out and just rebuilt the machines. Internet does work in safe mode on these affected machines.

Sorry for my delayed response, I am grateful for your help.

I am convinced the problem is macOS 13.6.5. The very same 13.5 installation file that I used successfully last August refused to run under 13.6.5.

Twice I have reinstalled 13.6.5 from the internet - so my hardware does connect, but 13.6.5, once installed prevents connection.

To do what I think you were trying to do and correct me firstly if your would 😎

Was Ventura 13.6.5 Already installed On the computer

Did you attempt to run the Ventura Full Version 13.5 Over the Existing Newer Version 13.6.5 ?

If yes, sorry but one can not Install an Older Versions Over the top of a newer version in the hope of Downgrading

To achieve this, would require Wiping the Drive to Zero ( Intel Computer ) and booting from an Bootable Installer of Ventura 13.5

On Apple Silicon Computers M1 / M2 / M3 , the process is somewhat more complicated but doable

Yeah, like PRP said you cant use an older installer to install over a newer version of the OS. And you can lay 13.6.5 over itself all day long but it doesn't appear to be fixing the broken internet issue. You need to wipe the disk before you reinstall next time you boot into internet recovery. That will fix the issue. It will also erase all your data.

I would suggest Not using the Internet Recovery to wipe and reinstall Ventura

Simple reason, the Reinstallation from Recovery Mode will pull down the Latest Available Version of Ventura.

Which would be Ventura 13.6.5 or a later version if one becomes available

I dont think theres a problem with that. Something about the update process broke the internet.

Once you wipe and reinstall with 13.6.5 the internet will be fine. We've done a dozen of them this week.

In that specific environment and possibly an MDM serve involved in the equation

Add in Corporate Requirements often mean using Third Party Security Software

Sorry, all bets are off as to the Ventura 13.6.5 actually Broke Internet Connection

In a Non MDM environment and No Third Party Security Software

Have updated 1 M1, 2 M2 machines from every single version of Ventura right through to and including 13.6.5 - No Broken Internet Connection here

Since that time to now, have upGraded each earlier to Sonoma 14.4 and still no issue

Add in a M3 which started with Sonoma 14.3.1 on first boot and upgraded to 14.4 - also no Internet Issues

Installing any version of macOS to an External Drive ( not mentioned until now ) and running the External Drive from External Drive changes this whole question.

Use an external SSD as your startup disk with your iMac or Mac mini

Above from a learned fellow Contributor

Understand, this can only be done from a Computer that Qualifies to run Ventura

Updating from 13.6.4 to 13.6.5 is causing loss of internet connectivity, even though we maintain an IP address. We thought it was our security software, but after removing that and updating the same thing happened. Whats up with macOS 13.6.5 update?
