Key already used for macOS Sierra but installed El Cap instead
So I went to install the public beta of Sierra and went to the website to get my key. Once I grabbed it, I thought I was updating to the new Sierra beta, but it updated to the latest public beta of El Cap instead. Now when I try to load Sierra it keeps telling me the key was already used and the AppStore says no updates available. How can I upgrade to Sierra??
