Warning
titleFull installer

Confirm the installer app is the complete installation (8+ GB) before continuing. If the app is less than 50MB, re-download the Install macOS Catalina.app.  A full installer may be downloaded through Terminal on macOS 10.15 devices.  Example to download the 10.15.4 full installer to the Applications directory:

Code Block
languagebash
titleDownload Full Installer
softwareupdate --fetch-full-installer --full-installer-version 10.15.4

Typically Apple only provide the latest point release of each Major OS version: 10.13.6, 10.14.6, etc.

Tip

Associate Fileset as a Kiosk association for the end users to install in their own time.
