Device Enrollment

Before you can manage devices with Jamf Pro, you need to enroll them in your Jamf Pro server7.

MDM Device Communication

Jamf Pro utilizes Apple's MDM framework to communicate with and manage enrolled devices8. This framework allows Jamf Pro to perform management actions that directly affect enrolled devices anywhere in the world, such as enforcing password requirements, providing services like Wi-Fi and VPN access, deploying apps and books, and restricting parts of the operating system8.

Here's how it works:

1. Jamf Pro sends a command to the Apple Push Notification service (APNs).

2. APNs notifies the target devices that a command from Jamf Pro is available.

3. The device reaches out to the Jamf Pro server to download and install the necessary configuration or perform the requested action.

4. The device notifies APNs that the command has been successfully executed.

5. APNs responds to the Jamf Pro server with the result.

Declarative Device Management

Apple has introduced Declarative Device Management (DDM) as a significant update to the MDM protocol9. DDM allows devices to communicate directly with management servers like Jamf Pro, improving the stability and security of device configurations, as well as the speed at which Jamf Pro receives status updates8.

With DDM, MDM servers can send more detailed, up-front instructions that tell the device how to behave under a set of conditions9. This means a device proactively takes action if it falls out of compliance and can send updated information directly to the server without waiting for a request9. As a result, device information is more accurate, and policies that keep a device compliant can apply faster9. This also cuts down network traffic considerably, resulting in a marked increase in performance and speed9.

DDM represents a shift towards modern device management, where devices are more autonomous and proactive in maintaining compliance and security9.

Configuration Profiles

Configuration profiles are a key component of Jamf Pro, allowing you to configure settings and restrictions on devices10. You can use configuration profiles to:

• Enforce passcode policies: Require users to set strong passcodes to protect their devices and data11.

• Configure Wi-Fi and VPN settings: Provide users with seamless access to corporate networks11.

• Restrict device functionality: Prevent users from accessing certain features or apps, such as the camera or App Store10.

• Configure email and calendar settings: Ensure users have access to their corporate email and calendar accounts10.

• Deploy certificates: Install certificates for secure communication and authentication10.

Policies

Policies are another essential aspect of Jamf Pro, enabling you to perform actions on devices12. You can use policies to:

• Install and update software: Deploy apps, updates, and other software packages to devices12.

• Run scripts: Execute custom scripts on devices to perform various tasks12.

• Send remote commands: Issue commands to devices, such as restarting or shutting down12.

• Manage local accounts: Create, modify, and delete local user accounts on devices12.

Smart Groups can be used to target policies to specific groups of devices based on criteria such as operating system version, installed apps, or user information12.

Smart Groups

Smart Groups allow you to dynamically group devices based on criteria such as operating system version, installed apps, or user information12. You can use Smart Groups to:

• Target policies and configuration profiles: Deploy policies and configuration profiles to specific groups of devices12.

• Generate reports: Create reports on specific groups of devices, such as devices with outdated software or missing security updates12.

• Automate tasks: Trigger actions based on device membership in Smart Groups, such as sending notifications or running scripts12.

Inventory Management

Jamf Pro provides comprehensive inventory information about your managed devices12. You can use this information to:

Troubleshooting and Best Practices

Troubleshooting Jamf MDM issues can be challenging, but there are some common issues and best practices to keep in mind.

Common Issues

Some of the challenges users face are: 13

• APNs communication failure: This can prevent configuration profiles from installing, VPP apps from installing, remote commands from working, and app installers from functioning13.

• Jamf check-in failure: This can prevent policies from running, inventory from updating, and cause issues with the Jamf binary13.

• Incomplete or partial check-in: This can stall the check-in process and prevent policies from installing completely13.

• Incomplete inventory: This can result in outdated inventory records, even if the device has recently checked in13.

Troubleshooting Configuration Profiles

If you encounter issues with configuration profiles, here are some troubleshooting steps you can take:

1. Check the install status of the command: In the device's inventory record, go to the History tab and then Management History. Check if the command to install the configuration profile appears under Completed Commands. If not, check under Pending Commands or Failed Commands.

2. Verify device scope: If there is no install command, navigate to the configuration profile and click Scope to ensure the device is included.

3. Check the distribution method: If the device is in scope and there's still no install command, click Options to verify the distribution method in the General payload. If the profile is set to be available in Self Service, it won't generate an install command until a user attempts to install it.

4. Check for pending commands: If the command is pending, confirm that the Apple Push Notification service (APNs) is working by navigating to Settings > Global Management > Push Certificates. On the device itself, check that it's turned on and connected to the internet.

5. Check for failed commands: If the command has failed, check the error message for clues about the cause of the failure.

6. Check for supervision requirements: Many restrictive settings require devices to be supervised. To check for supervision on a computer, go to System Settings > General > Device Management. On a mobile device, go to Settings and look for a message indicating supervision at the top left.

7. Check the profile level: In the configuration profile's General payload, check if the User Level option is chosen. If so, ensure the user is in scope and logged in.

8. Check for conflicting profiles: It's possible for devices to have more than one configuration profile installed. If there are multiple profiles with conflicting settings, the resulting behavior is undefined.

Best Practices

• Create unique configuration profiles: This reduces complexity and makes troubleshooting easier10.

• Use Smart Groups effectively: This allows you to target policies and configuration profiles to specific groups of devices12.

• Monitor device inventory: This helps you identify potential issues and ensure devices are up to date12.

• Enable Self Service: This empowers users to self-manage certain aspects of their devices2.

• Stay updated with Jamf documentation and support resources: This ensures you have the latest information and resources to effectively manage your Jamf MDM solution. Access these resources through the Jamf Nation community, online training catalog, and support portal2.
