I cover all macOS Monterey Supported Intel Macs including 2013-2015, 2016-2017 T1 and 2018-2020 T2.

This database will contain download links for macOS 12 full Installer pkg files (InstallAssistant.pkg). This file is the same full installer that you would download directly from the App Store for Intel and Apple Silicon M1 Mac Computers. The InstallAssistant.pkg is stored on Apple's servers and contains the full "Install macOS.app". Once downloaded, all you need to do is install the pkg and the full installer of macOS will be in your applications folder. This change was made when Apple revised the full installer for Big Sur. The InstallAssistant.pkg is not available for Catalina or Mojave.
