The IT User Support Group has had several calls from customers this morning regarding the endless reboot loop of their system after installing the latest High Sierra macOS update. Error message is,
“The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again.”
The system then enters an endless reboot and does not let you log into the computer.
