We're excited to begin using 10.18's new Application & Custom Settings payload to manage our Jamf Connect Login deployment. However, there's one undocumented key that we currently use in order to spruce up our login window by setting BackgroundImageAlpha to 0.
From what I can see, it appears that there must be a way to create new .json variants so that we can add this preference ourselves. But for the life of me I can't find anywhere that documents how it's done. Has anyone tried this yet?
