Installed from System Preferences in 10.14.2. First reboot reaches the installer but no progress bar running. Rebooted again, reached the installer and nothing again. Rebooted again but this time it takes a long time to reboot. Reached the installer, and this time the progress bar starts moving and time remaining shows another value. The installer goes all the way to the end and after that another reboot. This time you boot into MacOS 10.14.3. Calm down and don't panic. Total number of reboots was four for me. Remember, first one no move in the installer screen, second one no move in the installer screen, third one the installer goes all the way and fourth one you boot into 10.14.3.
