I see Apple released macOS Sierra 10.12.2 last month, I did not notice at first as I am running macOS Sierra on an unsupported laptop, a late 2008 unibody machine maxed out, it was not until I sat down at my more modern desktop machine I saw the update.
A minor hack of the installer enabled the install but I have for now unsubscribed from Apple updates to prevent them from upsetting this machine. You can use AUSEnabler” tool to subscribe to their already hacked updates if your willing to take the risk.
