INSTALL OS X YOSEMITE APP INSTALL
Note: We recommend to move the Install macOS.app into the /Applications folder, as we'll be executing commands from there.Mount it and you'll find the installer application. Once finished, you'll find in your ~/macOS-Installer/ folder a DMG containing the macOS Installer, called Install_macOS_11.1-20C69.dmg for example. This is going to take a while as we're downloading the entire 8GB+ macOS installer, so it's highly recommended to read the rest of the guide while you wait.
