Received a message that says 'this copy of the Install MacOS High Sierra application is damaged, and can't be used to install MacOs.' I have a Mac Air made
MacBook Air 13″, macOS 10.12
Open the Mac App Store and install any available security updates. If there aren't any, delete and redownload the installer; you may need to restart in Safe Mode(press Shift) and/or use a wired Internet connection.
