To achieve robust parental controls, the ideal path involves contacting Apple Support to: Understand the requirements for enrolling devices into Apple Business Manager (ABM). Access Apple’s comprehensive documentation on configuring an MDM for your family-owned devices. This approach ensures you get accurate, tailored advice and documentation directly from Apple. Combining ABM with a reliable MDM solution will allow you to implement and manage the advanced parental controls you're seeking effectively.
