Carbon Black Cloud Mac sensor code signing certificates are expiring on January 9, 2023.
Carbon Black Cloud Mac sensors installed and approved prior to January 9th, 2023 will continue to fully protect the endpoint past the expiration date, but if a sensor with an expired certificate is installed or approved (Sensor Versions 22.214.171.124 & 126.96.36.199 and lower), or if a sensor is manually reset (via repcli) after January 9th, 2023, then Network Extension functionalities will be unavailable
For any new installations or upgrades after January 9th 2023, please upgrade to the latest macOS sensor.
We will have new sensor versions available for download from the console within the next couple of weeks. Please follow this post for updated sensor availability and version numbers.
Sensors deployed in KEXT mode are not impacted
There are no code changes in the updated macOS Sensor releases; only the updated certificate, but we will change the build number to make clear which version has the newest certificate.
