Question: Problem installing macOS High Sierra
install completed, Mac air did a restart and the following error message appears;
macos os 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.
every time I click restart, same message appears and unable to get out of this message or use computer.
Any assistance appreciated. I am NOT very IT savvy.
