MacOS keeps trying to upgrade to Sequoia even with auto-upgrades disabled

Every morning I sit down at my Macbook Pro (M1, Sonoma 14.7) to find that it attempted to upgrade to Sequoia overnight. Luckily, I have an app that blocks it because it won't quit without acknowledging a prompt. I don't want to upgrade until the 15.1 release (or at least 15.0.1). I have "Install macOS updates" disabled, but still every night it attempts to install. Here is my auto-update screen (I even temporarily disabled Security Responses to see if that affected anything; it didn't):


What is going on? How can I prevent the auto-update?

I would suggest installing the free and open-source firewall Lulu (I am in no way associated with them), turn off 'Allow Apple Programs' and then only block 'installd', 'softwareupdated' and 'systemmigrationd' (I think). At least for me, with these settings the App Store still works fine.

You should Have to do this.


If you have enough Empty Space on the computer ( about 14.54 GB ) as that is the size of the Full Sequoia


Manually download the Install Sequoia Application


Leave it alone


This may sort of Trick the Software Update Applet to thinking it was installed


When ready, Drag the Install Sequoia Application from Applications folder


Then commence the upGrade to whatever the next version of Sequoia is


Terminal command below


softwareupdate --fetch-full-installer --full-installer-version 15.0

There are those that believe blocking the builtin Apple Software Update applet via a third party firewall s a good thing.


Perhaps of one is using Beta Software that would be appropriate


Though, otherwise it is generally not the best of ideas


When a Fix is proved by Apple


It has usually been Tested on their Test Machines which mean it will usually work to fix Bugs and or Security Issues
