So about 25% of machines that are suffering from an error when applying the "macOS High Sierra 10.13.3 Supplemental Update" released today.
"macOS could not be installed on your computer"
"The path /System/Installation/Packages/OSinstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again"
Restarting just brings it back to the same screen. the only fix I've found is to restore to a snapshot.
Anyone have any ideas as to why this is happening?
