macOS 10.12.1 is now available at AS. We'll see how the update goes.
Direct update and everything ok for me too (I am still having the glitches issues).
What glitches are you having? I was having very subtle video glitches, but 10.12.1 seems to have fixed it. Also, I was having an icloud connection loop on one of my machines that, for now, is resolved.
