I setup a do not disturb to run all day everyday. I have not had a notification to update to Tahoe in over a month.
I don't even have any special handling set and haven't had any Tahoe prompts beyond maybe the first one. I often forget that I'm not on the latest anymore.
With all “auto updates” off I was getting a notification at least once a day.
I’d like to know what rules you use to prevent Tahoe updates while allowing Sequoia updates. It would be quite useful to me, and I guess, to others here who use Little Snitch.
Just enable the Sequoia developer/beta channel. You won’t see other updates then.
