April 22nd update: Sensor 126.96.36.199 will not be available after 4/20/2022. VMware Carbon Black strongly recommends not upgrading to macOS 12.3 until sensor version 188.8.131.52 is installed.
On Monday March 14th, Apple GA'd macOS version 12.3. Carbon Black Cloud has identified in some cases that a sensor enters bypass mode immediately after upgrading to macOS 12.3, which results in feature loss. Additionally, the bypass state in this scenario does not properly display on backend. VMware Carbon Black strongly recommends not upgrading to 12.3 until the release of the 3.6.2 sensor which will resolve the issue.
During pre-release builds, Carbon Black Cloud identified changes that Apple has made in version 12.3 with regards to their internal protocols. In some circumstances, these changes resulted into the sensor silently going into bypass mode while still appearing as active from the console. While the sensor is in bypass mode, the endpoint will not be protected. If encountered, this issue can be resolved by upgrading the sensor to version 184.108.40.206.
