Just as a reminder, I think a "Combo" update is always safer and therefore better than an App Store updater. The former does a clean install. The latter asks lets updater decide what parts you need to update. While the App Store updater usually works, I don't understand why we should trust the coders to know everything that's changed in our own set up. The "coders" and their quality control procedures haven't been running at 101% lately...Your very own macOS High Sierra 10.13.2 Combo Updater (https://support.apple.com/kb/DL1944?locale=en_US)
