I signed up for the beta program. Once macOS Sierra 10.12 came out on the 20th I downloaded it thinking that would stop the beta updates it hasn't. My Mac just downloaded the latest while I was at work. So I went to the app store and downloaded the macOS Sierra 10.12.2.. Then I was given a choice in App Store preferences to hide or not to hide future beta updates so I picked don't want them hide them. Will it stop downloading or just hide the fact it did? I just want to opt out.
