Computer PreStage Enrollments
A PreStage enrollment allows you to create enrollment configurations and sync them to Apple. This enables you to enroll new computers with Jamf Pro, reducing the amount of time and interaction it takes to prepare computers for use.
Before you can use a PreStage enrollment, you need to integrate Jamf Pro with Device Enrollment (formerly DEP). This creates a Device Enrollment instance in Jamf Pro. For more information, see Integrating with Automated Device Enrollment. Only computers associated with a Device Enrollment instance can be enrolled with Jamf Pro using a PreStage enrollment.
After creating an Automated Device Enrollment instance, you need to create a PreStage enrollment in Jamf Pro for the computers you want to enroll. Creating a PreStage enrollment allows you to configure the enrollment settings and customize the user experience of the Setup Assistant. You can also specify the computers that should be enrolled using the PreStage enrollment and automatically add computers newly associated with the Device Enrollment instance to the PreStage Enrollment. Only computers with macOS 10.10 or later that are associated with the Automated Device Enrollment instance can be enrolled with Jamf Pro using a PreStage enrollment.
