Earlier quoted context omitted.
OS X keeps harassing me to update to the latest version because I have automatic updates on and haven't turned the notifications off, but it hasn't gone and downloaded the new OS pre-emptively without my consent. Asking first wouldn't hurt, you know!
Then it's not really "automatic updates". If it was truly automatic, it would download and even install without asking because you already said yes.
Is that a better design? Especially considering Apple routinely automatically downloads updates that are also in the gigabyte range.
