I suppose eventually my Mac OS Auto Update and Install will eventually do its thing. My iMac M3 is still on Sonoma 14.6.1.
 
I'm still on 15.0.1 (24A348). M1 Pro.

"Your Mac is up to date." is what it still tells me, as of November 19th, 2024. No 15.1.1, no 15.1.

I can manually download 15.1 (24B83) or 15.1.1 (24B91) using something like Mist, but I figured the built-in updater would work.
i put ipsw and full installer links in post #4 if you want to get it that way
 
patches released today
iOS 18.1.1 (Build 22B91) - November 19, 2024
iPadOS 18.1.1 (Build 22B91) - November 19, 2024
iPadOS 17.7.2 (Build 21H22) November 19, 2024
macOS 15.1.1 (Build 24B91 | 24B2091) - November 19, 2024
visionOS 2.1.1 (Build 22N591) - November 19, 2024
 
i'm on 15.2 beta 3 already so probably won't install 15.1.1 but will still download the 15.1.1 full installer to make bootable usb

presumably the next 15.2 beta will have the security fixes

would you describe installing 15.1.1 over the top of 15.2 beta 3 an upgrade or downgrade?

downgrade in terms of version number, but 15.1.1 came out after 15.2 beta 3 with security fixes, so upgrade in terms of security.

but then you lose the extra ai stuff in 15.2 so i'll wait for next beta - you have to kind of agree to live on the wild side when installing betas, accepting more bugs/vulnerabilities
 
iPhone - updated.
iPad - updated
M4 mini - updated but took a few minutes to appear
M1 MBP - no update even visible!

All on same network at home.

Editing to add:
M1 MBP came through about half an hour later and applied.

I wonder what happened to the "rapid security response" update mechanism that Apple implemented in Ventura and iOS/iPadOS 16. I feel like it's only been used once, maybe twice, and I would think this kind of security fix update would be a perfect fit for the rapid response mechanism.

I am also on 15.2 Beta 3. You can't install just a lower version over a higher one anymore. This is really annoying. I don't think you have to fear anything. Those security things are mostly for very rare cases and normally nothing ever happens if you don't update your Mac ever.

Yes, what is this? I never saw it had been used. At least I didn't get any notification.

I don't know why it is so hard for Apple to deliver updates.
Consider this: Microsoft has paid to restart the Three Mile Island nuclear reactor in order to provide enough electricity -- 835 megaWatts -- for their data centers.

So it's feasible that Apple cannot provide on-demand multi-gigabyte software updates to every single iPhone, iPad and Mac computer all at once.
