Signing in to an Apple Account must be completed by the user directly on the device. This action cannot be performed remotely via a Jamf mobile device management (MDM) solution or portal, including Jamf Pro, Jamf School, Jamf Now, and Elevate, as Apple Account authentication is designed to be a user-initiated process.
For related information, see Sign in to your Apple Account on the web or in your device settings on the Apple Support website.
