  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
