First ever post! I would like to have a policy that places the installer in the Applications folder of macs in preparation for upgrading. One method I will use for Macs not yet on Catalina, is to create a package with the Install macOS Big Sur.app.

When I place the installer app (a 12GB file) in Composer, the package it builds is only 15MB. I am using Composer 10.25.1 on a Catalina mac. Thoughts?
