In 10.9.2 (not sure about earlier versions of .9) I can find no way to stop the nagging software update requests from the App Store. I've heard of people uninstalling software which works in some cases. But for some apps I just don't want the latest version.
Has anyone found a fix? I don't care how complicated it is, I just want to stop hearing from the App Store. I really don't like the App Store.
