Apple released the 10.14.1 update to Mojave today along with iOS 12.1, a Watch OS and TV update. I have installed all of these without incident. When you request the iOS update it may say “Update Requested” for a while, but it will update eventually. I am hoping the MacOS Mojave 10.14.1 update will alleviate my Mojave OS freezes that I have been having. YMMV, but I say go do a bunch of updates when you have time. The 10.14.1 update has lots of security fixes. There is a security update for macOS Sierra and High Sierra.
