How to add devices to Apple Business Manager (ABM)?

Mobile Device Manager Plus empowers IT admins to seamlessly integrate and incorporate a wide range of devices, such as iPhones, iPads, Macs, and Apple TVs. This integration streamlines the process of bulk device onboarding for your organization. This comprehensive guide outlines the essential steps to efficiently manage your devices through Apple Business Manager (ABM) and Mobile Device Manager Plus.

Apple Business Manager (ABM) is a cost-free portal offered by Apple. It is tailored to cater to the needs of enterprises, offering a simplified and automated approach to enrolling and deploying corporate Apple devices including iOS, iPadOS, macOS, and tvOS devices. In a similar approach, Apple provides Apple School Manager (ASM), a dedicated service designed for educational institutions, including schools and other establishments focused on education. ASM simplifies the mass enrollment and administration of Apple devices employed for educational purposes.

Previously known as the Apple Device Enrollment Program (Apple DEP), Apple Business Manager (ABM) affords admins the flexibility to seamlessly add devices to the platform, either automatically or manually. This facilitates over-the-air management, ensuring that your devices are efficiently integrated and ready for streamlined administration within your organization.

Prerequisites

Ensure the following pre-requisites are met to enroll Apple devices using Apple Business Manager (ABM) enrollment:

• Apple Business Manager must be available in your country. Find the list of countries where ABM is supported here.
• The devices must be purchased from Apple or its authorized resellers. You can view the list of Apple's preferred resellers here.

In case of devices purchased neither from Apple directly nor from its authorized resellers, you can still add devices to Apple Business Manager (provided they're running or capable of running iOS 16.0 or later versions) as explained here. If you have devices running iOS 15.0 or below, follow the steps mentioned here.

NOTE: The steps mentioned in this document are also applicable to the Apple School Manager portal.

How Apple Business Manager (ABM) works?

The process of managing with Apple Business Manager first starts, when your organization purchases Apple devices from Apple or from Apple authorized resellers. You have to log into your Apple Business Manager account. If you already have an account with Device Enrollment Program, you can migrate to Apple Business Manager by following the prompts available on your DEP portal. You have to register MDM with the Apple Business Manager portal. Once you have registered the MDM server, secure communication is enabled between the MDM server and the Apple portal. This is used to synchronize the details of devices, purchased by your organization. When you find the devices synced from the Apple portal, you can assign it to users. Whenever the devices are activated, all restrictions and configurations imposed using MDM are automatically installed on all your devices over-the-air (OTA). By configuring ABM, you can ensure all the organization's devices are managed by MDM by default as soon as they are activated.

• If you do not have an ABM account, you can create one here. To know your DUNS number (which is one of the prerequisites), refer to this. You can also refer to this document to fully understand Apple Business Manager.
• ABM sync happens over a series of requests sent from ManageEngine MDM, and Apple's ABM server will track the requests to check if IP changes. If a load balancer is being used, this sync will fail. So, you need to allow the URL mdmenrollment.apple.com to pass using the same outgoing IP address so that ABM sync occurs.

Benefits of Apple Business Manager (ABM) Enrollment

• The device is Supervised which means you have additional control over the device. For detailed information on Supervised Devices, refer to this.
• The devices can never go unmanaged from MDM at any point, even if the device is factory reset.
• Users can skip initial setup steps for a faster device activation
• Out-of-the-box enrollment to ensure devices are usage ready immediately upon activation.

Integrating Apple Business Manager with MDM

After creating your organization's Apple ID and deployment account by following the steps mentioned in the ABM Program Guide, you need to carry out the steps outlined below, to seamlessly enroll and manage your organization's corporate Apple devices into MDM using Apple Business Manager enrollment.

First, you need to link the MDM server to your organization's ABM account. For this:

• On the MDM server, navigate to Enrollment -> Apple -> Apple Enrollment (ABM/ASM).
• Download MDM Public Key which has to be uploaded on Apple Business Manager portal.

• Sign in to Apple Business Manager portal using your organization's managed Apple ID.
• Click on Preferences -> MDM Server Assignment and navigate to Add MDM Server, to create a virtual server on the portal.

• Enter a name for the server based on your organization's locations or departments.
• Now, you need to upload MDM Public Key, downloaded earlier from MDM and click on Save.

• To download a server token, click on the Account Name, and navigate to Preferences > Your MDM Servers and select your server. Next, click on Download Token. This server token needs to be uploaded to the MDM console.

• Navigate back to your MDM console and add the Server Token under Upload Server Token.    
• Specify the e-mail address to receive notifications regarding Server Token expiry.
• Click on Upload to complete the uploading of the Server Token. You can configure the device activation settings as explained here.

Setting a default server

Using Apple Business Manager you can automatically assign the purchased devices to particular servers once they have been added to the portal. Additionally, you can select different servers based on the type of device being enrolled. It is recommended to assign different types of devices to different servers. All of these servers can be integrated and managed using MDM. To select a default server for a particular type of device-

1. Select the required server from the list and click on Edit.
2. Under Default Device Assignment, select the device type.
3. Click on Apply to ensure all the devices added to the portal are assigned to this server.

How to add devices to Apple Business Manager portal?

One of the advantages of adding devices like iPhones, iPads, and MacBooks to Apple Business Manager is that these devices can be enrolled without any user interaction. Learn how to add devices to ABM from the steps below.

There are two methods available to add devices into Apple Business Manager. IT admins can use any of the following methods to add devices to Apple Business Manager:

• Adding reseller details to the ABM portal
• Manually adding devices in Apple Business Manager portal to MDM

Read on to find out how to add devices like iPhones, iPads, and MacBooks to Apple Business Manager using reseller details or manually.

Adding Reseller details into the ABM portal

To add devices to Apple Business Manager, the reseller details must be added to the ABM portal. So every time devices are purchased from the same reseller, the devices are added to the ABM portal and in turn, to the MDM server due to the integration of the ABM portal with the MDM server.

Note: On ABM, only the Administrator or Device Manager roles can add the reseller details.

1. Log into ABM using your organization's credentials. The option to add resellers is only available on the Device Manager's console, apart from the Administrator's console.
2. Click on Settings -> Device Management Settings. Navigate to Customer Numbers to add your Apple Customer Numbers and ABM/DEP Reseller IDs.
3. Click on Apply, to save the details.

How to manually add devices in Apple Business Manager to MDM?

After linking your MDM Server to the Apple Business Manager (ABM) portal, if you have devices purchased before integrating the portals, you can add devices to Apple Business Manager by following the steps mentioned below:

1. On your Apple Business Manager portal, navigate to Devices.
2. From the list of available devices, select the devices to be added and click on Edit Device Management.
3. In the Assign to server field, select the MDM server which was configured earlier and click Continue

The Apple devices are now added to the MDM server, automatically.

For adding iOS/iPadOS devices to ABM which are purchased from sources other than authorized Apple resellers, check here.
For adding Mac devices to ABM which are purchased from sources other than authorized Apple resellers, check here.

Note: To distribute specific profiles and apps to a group of devices, assign all the devices present in an MDM server in ABM to a group in MDM and dsitribute the required profiles and apps to that group.

Device Activation Settings

On adding devices to MDM using Apple Business Manager enrollment, all the devices are enrolled successfully. Before the enrollment is complete, you have to configure the settings to be applied to the devices, on device activation. You can create and apply these settings to all your devices at one go, by following the steps mentioned below:

• On the console, navigate to Enrollment -> Apple -> Apple Enrollment(ABM/ASM).
• Complete the required fields displayed under Device Activation Settings.

• Authenticate and auto-assign users on device activation (Applicable only for On-premises): If you want to automate the user assignment process, enable this option and select the group to which the device is to be added upon enrollment. This allows the users to assign devices to themselves, on device activation, using their Active Directory credentials.
• Skip these configurations during device setup: During device activation, you are required to follow some initial setup steps. With MDM, you can optionally skip selective steps or completely skip the setup. Assuming your organization wants to prevent users from setting up Siri during the setup assistant process, you can do so by selecting Siri from the list of configuration settings provided. The list of configuration settings is given below.

Mac Account Settings

As imaging for deploying Mac devices has been stopped by Apple, MDM provides a quicker and more efficient means of deployment by automating the creation of a local admin account on device activation. The local admin account created on the device has the following benefits:

• Device maintenance is simplified as security checks and device audits can be carried out without user intervention and during non-work hours, thereby preventing loss of productivity.
• The admin can install, update and also remove system configurations.
• Troubleshooting system issues and user account problems, becomes easy and quick. In case of forgotten password, the admin can assist the users by resetting the password.
• User accounts can be added and removed as and when required. For instance, the user account of the employee who leaves the organization can be removed from the corporate device and a new account created, before handing over the device to the next employee.

To configure a local admin account, enable Mac Account Settings and provide the required fields the details of which have been given below.

Click Create. Now, the configurations and settings get applied to the devices.

Syncing Devices

After creating the ABM profile and applying it to devices, you can choose to Sync Devices by navigating to Enrollment-> Apple -> Apple Enrollment (ABM/ASM).

Mobile Device Manager Plus will automatically sync with the Apple Business Manager every 24 hours. On syncing, all the settings configured in the ABM portal will get applied to the devices and listed on the MDM console. Admins can schedule this sync time according to the time when resellers add the devices to the ABM portal. Follow the steps mentioned below to schedule ABM sync time:

• On the Mobile Device Manager Plus Console, navigate to Enrollment > Apple Enrollment (ABM/ASM).
• On the top right corner, click on Edit Sync Time or click on the Settings tab.

• Enter the Sync Time based on your preference and click on the tick icon to save.

The devices will be successfully synced from the ABM portal based on the scheduled sync time and listed on the MDM server.

In case the devices are not new, the devices should be factory reset, in order to be configured using ABM.

 To reset a Mac device, follow the below steps:

• Mac with Apple Silicon
• Intel-based Mac

Assign Users to Devices

You can assign all the devices to individual users manually by navigating to Enrollment -> Apple -> Apple Enrollment (ABM/ASM) -> Devices. The alternate and easier option is to add users through a CSV file. You can also automate user assignment if you are using on-premises MDM version. Automated user assignment ensures the users are authenticated and self-assigned when the device is enrolled. This option must be enabled when ABM is configured or if already configured, you can enable the option from ABM settings. The only pre-requisite is, Active Directory must be configured in MDM. When enrolling the device using ABM auto-assignment, the user name to be provided on the device must be in the format: domain name\user name.

While assigning the users to devices, these devices can also be added to groups to automate the distribution of apps, profiles, and documents to devices. The devices can also be simultaneously added to multiple groups while assigning users.

Note: In order to distribute different set of apps and profiles to devices of different platforms(iOS, macOS, etc.) ensure each ABM server to be set up under a separate group as ABM's Default Device Assignment automatically assigns specific types of devices under specific MDM servers.

Sample CSV Format

SERIAL_NUMBER,USER_NAME,DOMAIN_NAME,EMAIL_ADDRESS,GROUP_NAME
C07Q853LG9RM,ANDREW,,andrew@zylker.com,zylker_drivers

NOTE:

1. The fields Serial Number, User Name, Email Address and Group Name are mandatory. All the other fields are optional. Ensure the specified group name is already created in the MDM server. If values are not provided, default values will be taken.
2. The default values for various non-mandatory fields are: 
   Domain Name -- MDM
   Owned By -- Corporate
3. If multiple groups are specified, the group names must be separated with a slash (/)
4. The first line of the CSV is the column header and the columns can be in any order.
5. Blank column values should be comma separated.
6. If the column value contains comma, it should be specified within quotes.

Supervision Identity Certificate

Supervision Identity contains the identity of the organization that manages the device and hence is unique to every organization. This identity is associated with the supervised devices during enrollment via ABM/ASM. The host Mac machine that has the matching supervision identity certificate installed will be considered supervising Mac and USB Access to supervised devices will be restricted only to the supervising Mac. Hence installing the supervision identity certificate on a Mac machine lets you authenticate and trust the machine, allowing you to securely pair iOS/iPadOS devices enrolled using ABM with them, even if USB pairing is restricted on the devices.

Steps to download Supervision Identity Certificate

1. On the Console, navigate to Enrollment -> Apple Enrollment (ABM/ASM)..
2. In the Settings tab, click on Download under Supervision Identity Certificate.
3. Once downloaded, you can import the certificate to Keychain Access.

Steps to import Supervision Identity Certificate

1. Open the Keychain Access app on a host Mac machine to which you want to pair the devices and click on File -> Import Items.
2. Select the certificate and click Open.
3. Enter the password displayed on the console while downloading the certificate.

You have now successfully imported the certificate to your Mac machine and the imported certificate will be listed under My Certificates in Keychain Access app.

Regenerating Supervision Identity Certificate

Once the supervision identity is associated with a device, it cannot be changed later. Hence, the devices will need to be erased and re-enrolled if you are regenerating the certificate. Thus, ensure to download and have a back up of the existing certificate to pair your currently managed devices with Mac machines if you are regenerating the certificate. Only the devices enrolled after regenerating the certificate can be paired using the new certificate

Steps to regenerate Supervision Identity Certificate

1. On the Console, navigate to Enrollment -> Apple Enrollment (ABM/ASM)..
2. In the Settings tab, click on Regenerate under Supervision Identity Certificate.
3. Once regenerated, you can import the certificate to Keychain Access as explained above

Remove Devices from the ABM portal

To unmanage the device, the admin must remove the device from the MDM server. Once the device is removed from the MDM server, the device is automatically removed from the ABM portal.

The devices that are enrolled with one ABM account cannot be enrolled in another. Therefore, these devices must be removed from the first ABM account before enrolling into another. Follow the steps given below to remove the devices from the ABM portal.

1. Log into the ABM portal and click on Devices.
2. From the list of available devices, select the device to be unassigned and click on Edit Device Management->Unassign. If you are trying to remove multiple devices, you can upload a CSV file with the device details.
   This unbinds the device from this ABM account.

Apple Business Manager Unassign vs Release

To remove the devices, always select Unassign device and not Release device. Release device should be used only if the device is lost or permanently damaged and will never be part of any workforce. Releasing devices is a non-reversible action and once disowned the device can never be part of an organization.
