We are trying to disable the Apple ID and Siri screens of the Apple Setup Assistant on first boot and have not been successful.
Most of the discussions on this issue have been around disabling these prompts when a new user logs in. We actually want to keep the Apple Setup Assistant as-is for freshly imaged machines in order to keep the setup process as close to our DEP workflow.
Does anyone know what DEP does to actually skip steps in the Apple Setup Assistant and if it can be done via the shell for non-DEP'd machines?
