macOS 10.13.3 Supplemental Update

Apple just released a 10.13.3 Supplemental Update which is a fix for a messaging problem. However, there are other things not listed by Apple that are fixed in this update. Here is an article listing some of them. I have installed the update on my Macs and Restarted. As far as I can tell there are no problems. It is probably a good idea to install this Supplemental as soon as possible.
