Installation Instructions

To install the new sensor, please follow the steps below. For unattended installs using a Mobile Device Management (MDM) solution, use the following inputs to create profiles for preventing endpoint user prompts. More information can be found here.

  • Plug-in ID: com.carbonblack.es-loader
  • System Extension Bundle ID: com.carbonblack.es-loader.es-extension
  • Application Bundle ID: com.carbonblack.CbOsxSensorService
  • Apple Team ID: 7AGZNQ2S2T

To install the sensors on to your server, perform the following procedure:

  1. Ensure your VMW CB EDR YUM repo is set appropriately:
    1. The VMW CB EDR repository file to modify is /etc/yum.repos.d/CarbonBlack.repo
    2. Baseurl = https://yum.distro.carbonblack.io/enterprise/stable/$releasever/$basearch/
  2. On the VMW CB EDR server, clear the YUM cache by running the following command: yum clean all
  3. After the YUM cache has been cleared, download the sensor install package by running the following command: Run yum install --downloadonly --downloaddir=<package local download directory> <package>

    Note: <package local download directory> is a directory of your choice

    <package> is replaced by cb-osx-sensor

  4. Install the new sensor package on the VMware Carbon Black EDR server by running the following command: rpm -i --force <package>
  5. Make the new installation package available in the VMware Carbon Black EDR server console by running the following command: /usr/share/cb/cbcheck sensor-builds --update

    Note: If your groups have Automatic Update enabled, the sensors in that group will start to automatically update.

This new sensor version will now be available in the VMware Carbon Black EDR server console. For any issues, please contact VMware Carbon Black Technical Support.

Resolved Issues

  • CB-35578, CB-39127: Resolved an issue where the CbOsxSensorService could be banned

  • CB-37201: NFS or SMB shares could not be unmounted while running the sensor

  • CB-14033: An internal sensor process, CbDigitalSignatureHelper, would continually be reported to the server

  • CB-36824: Internal sensor events from /var/lib/cb were reported to the server

  • CB-37225: Crash logs would be generated on server-initiated sensor upgrade or downgrade

  • CB-37631: The sensor would crash when computing a hash for binary upload

  • CB-37529: Filemods could not be disabled from the server UI when running the sensor as a system extension

  • CB-37989: Users were prompted for permission to allow the sensor to filter network content

  • CB-37729: Sensors not managed by an MDM solution did not have permission to filter network content

  • CB-36229: Users were not notified that a sensor was staged for execution but did not reach a running state

Known Issues

  • CB-32640: When content filters are installed and enabled or uninstalled and disabled, existing connections are terminated

    This is by design per Apple.

  • CB-32640: Uninstallation of the sensor should be done via the Server

    Manual uninstallation through Terminal will require the user password to be entered. This is by design per Apple.

  • CB-8908: The EDR macOS Sensor does not store Live Response activity in the sensor.log file by default

    Users can monitor Live Response activity using the live-response.log found under /var/log/cb/audit on the EDR server. Additionally, users can enable more verbose logging of the sensor.log file to capture Live Response activity on the Mac endpoint. Note that enabling verbose logging can quickly consume the specified sensor.log size and should be used cautiously, as enabling can lead to shorter retention of audit information. This verbose logging can be enabled by modifying the logging.config file under /var/lib/cb to to set the following parameters: minloglevel: 0,  V:0.

  • CB-37441: Filemods to /dev/dtracehelper and /dev/ttys000 are still reported even when an exclusion is in place

  • CB-38779: All childproc events are reported to the server even when Retention Maximization is enabled

  • CB-37032: Network events are not captured when using a VPN under Big Sur and Monterey

  • CB-37962: macOS Get Info command reports sensor version as 1.0

  • CB-38251: Sensor does not filter known dylibs on macOS Monterey
