OSX Full Installers

A few years back I posted a guide on how to create a macOS OSX USB installer. The steps are basically the same even after a few iterations, so for today, I will just create a walkthrough on how to download full installers.


  1. Open the terminal.

2. Check the available OSX versions using this command:

softwareupdate --list-full-installers

3. To start the download use this:

softwareupdate --fetch-full-installer --full-installer-version <OSX Version>

4. Wait for it to finish.

You can now access your Full Installer in the Applications folder.
