Three times today tried downloading the macOS Mojave installer, to a MacBook Pro (15-inch, 2018) running Mojave and each time it downloaded and reported “application is damaged damaged and can’t be used to install mac OS.” I want to have a fresh installer so I can install Mojave on a new volume to run Parallels Desktop for some 32 bit apps. To get the full installer: Method 1. Start the installer, which will download the missing files; Quit when prompted to restart; Copy (or move) the downloaded files from /macOS Install Data to a new SharedSupport folder inside /Applications/Install macOS High Sierra.app/Contents/. El Capitan Installer. Mac operating system’s twelfth major version is the El Capitan Installer (version 10.11). All the Mac computers which don’t have the privilege to upgrade to MacOS High Sierra or the computers that need to upgrade to El Capitan first, can download this twelfth version on the computer.
