Custom payload settings
Use the Custom payload to specify preference settings for apps that use the standard property list (.plist) format for their preference files.
You can use this payload to add specific keys and values to an existing preferences property list (.plist) file. Not all apps work with managed preferences, and in some cases only specific settings can be managed.
If you’re not sure how to specify a key for an app, change the setting using the app, and then examine its preference file using Xcode to see how the setting is represented.
You can upload a preference property list (.plist) file directly into the Custom payload, but you should remove non-manageable settings using Xcode before importing into the payload. To import the payload, click Upload File and locate the preferences file you want to import.
This payload doesn’t prevent you from setting invalid preference settings, so make sure you test your changes before deploying the profile.
