[Carbon Black Cloud] macOS Big Sur Functionality Overview
Beginning in macOS 11, the Carbon Black Cloud macOS sensor (v3.5.1) will operate by default in user-space via System Extensions (user-space) instead of Kernel Extensions (KEXTs) used in prior versions of the agent.
As a result of this change, some functionality will be temporarily unavailable when using the sensor in System Extension mode on macOS 11 and later. Using the sensor in KEXT mode achieves the same functionality on macOS 11 as seen in older operating systems and is recommended for customers who plan to immediately adopt macOS 11.
While we plan to deliver the additional functionality gradually to avoid the performance implications that come with operating in user-space, we plan to deliver a large subset of the functionality detailed in the matrix below in a follow-on release in Q1 2021.
Please be advised that unless otherwise specified, documentation related to macOS functionality on the Carbon Black Cloud pertains to macOS 10.15 and earlier or to functionality delivered via the KEXT on macOS 11.
This matrix outlines macOS functionality on the Carbon Black Cloud. The functionality detailed in the macOS 11 column pertains to the sensor’s functionality in user space (System Extension) in the initial macOS 11-compatible sensor release (v3.5.1). For functionality provided via the kernel extension, please refer to the macOS 10.12 - 11 column.
We will keep this matrix updated as we release functionality. Please be advised that any delivery timelines specified below are estimates and subject to change.
