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?
