Silent Install X9 on macOS


I apologize if this has been asked and answered before. Searching the forums for “silent” and “install” produces many results, with no clear answer. I have to deploy X9 to several hundred Macs. The full download is a DMG and the installer script inside of the “Install” file does not seem to have a silent option. Running it from the terminal just starts the install wizard. Using pkgbuild on macOS offers no further imrovement because it will just package the installer APP, and not the executable itself, which is usually just copied into applications. How are people deploying this application? What am I missing?
