Quit install high sierra os application?
Trying to install High Sierra I get message: 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.
I have an iMac 2011. Tried force shutdown, but each time it reopens it is still trying to install the update and goes to the same message in a loop. Please can you advise what to do? Thanks
iMac 27", macOS 10.12
