Install the Cortex XDR Agent for Mac

Before installing the Cortex XDR agent on a Mac endpoint, verify that the system meets the requirements described in Cortex XDR for Mac Requirements.
Install the agent using a software distribution tool of your choice (such as JAMF) or using the following workflow:
  1. Download the installation package you want to install from Cortex XDR.
  2. Copy the installation package to the endpoint on which you want to install the Cortex XDR agent software.
  3. Unzip the installation package.
  4. (
    ) Configure a Cortex XDR agent specific proxy on the endpoint.
    If you are deploying Cortex XDR in an environment where the agents communicate with Cortex XDR through a proxy, you must assign the proxy IP address and port number during the agent installation on the endpoint.
    1. Locate the
      file in the unzipped installation folder.
    2. Edit the
      • To enforce a proxy specific to the Cortex XDR agent, enter your proxy IP address and port number. You can assign up to five different IP addresses per agent, and the proxy for communication is selected randomly with equal probability.
      • To install an agent communicating through the Palo Alto Networks Broker Service, enter only the broker VM IP address and port number 8888.
    3. If needed, you can later change the proxy settings from the Cortex XDR management console.
  5. (
    ) Disable Live Terminal, script execution, and file retrieval on the endpoint
    You can permanently disable the option for Cortex XDR to perform all, or a combination, of the following actions on endpoints running a Cortex XDR agent: initiate a Live Terminal remote session on the endpoint, execute Python scripts on the endpoint, and retrieve files from the endpoint to Cortex XDR. Disabling any of these payloads in the
    file is an irreversible action, so if you later want to enable the action on the endpoint, you must uninstall your Cortex XDR agent and install a new agent with the corresponding values in the
    1. Locate the
      file in the unzipped installation folder.
    2. Enter the value
      for this tag, as follows:
      • To disable a specific action, update only the value of the relevant tag:
        <restrict_live_terminal>1</restrict_live_terminal> <restrict_script_execution>1</restrict_script_execution> <restrict_file_retrieval>1</restrict_file_retrieval>
  6. Install the Cortex XDR agent software.
    1. Run the
      Cortex xdr.pkg
      installation file.
    2. Click
      to proceed with the installation.
    3. If prompted to confirm the destination, click
    4. Click
      to begin the installation.
    5. Enter the
      User Name
      of the administrator with access to install software on the endpoint, and then click
      Install Software
    6. (
      macOS 10.13 and later versions
      ) Allow Cortex XDR to install system extensions:
      1. Dismiss the
        System Extension Blocked
      2. Go to
        System Preferences
        Security & Privacy
        and select
        macOS 10.15 only
        ) When you install the Cortex XDR agent on endpoints running mac10.15, allowing Cortex XDR to install system extensions requires an additional step. After you select
        , another window opens listing the Palo Alto Networks system software that you must approve. In this macOS release, instead of the actual file name
        , you will see
        Placeholder developer
        . Select all items on this list and click
    The Cortex XDR agent logs any installation errors to
    . If installation fails for any reason, you can view this log to better understand the cause of the installation failure.
  7. After the installation completes, verify your connection.
    1. To open the Cortex XDR agent console, click the agent icon in the menu bar, and select
      Open Console
    2. Click
      Check In Now
      to initiate a connection with your tenant of Cortex XDR. If successful, the
      Last Check-In
      field updates to display the recent check-in date and time.
      If the Cortex XDR agent does not connect to Cortex XDR, verify your internet connection and perform a check-in on the endpoint. If the agent still does not connect, verify the installation package has not been removed from the Cortex XDR management console.
  8. (
    macOS 10.15 and later versions
    ) Grant full disk access.
    Due to changes in the security settings of macOS 10.15, you must allow the Cortex XDR agent full disk access on your endpoint to enable full protection. If you do not authorize the agent full disk access on your endpoint, the agent provides only partial protection of files in the
    directory. The first time the agent detects an attempt to run an executable file located in another protected location on the endpoint as part of the anti-malware flow, macOS will deny the Cortex XDR agent access and prompts the user to grant full disk access.
    You can grant the Cortex XDR agent full disk access manually or using a third-party tool such as JAMF.
    To grant the Cortex XDR agent full disk access locally on the endpoint:
    1. Go to
      System Preferences
      Security & Privacy
      tab, and select
      Full Disk Access
    2. To make changes, click lock icon ( ) on the bottom left, enter your credentials, and
    3. Navigate to
      Macintosh HD
      Application Support
    4. Select
      and add
      /Applications/Cortex XDR.app/Contents/Library/SystemExtensions/com.paloaltonetworks.traps.securityextension.systemextension
    5. When you’re done, click to save your changes and stop editing.
