Environment

Release : 15.7, 15.7 MP1

Component : DLP Enforce Server and DLP Endpoint Agent.

Cause

DLP Endpoint Agent was generated from DLP Enforce Server 15.7 or 15.7 MP1.

Resolution

We support macOS Big Sur starting with DLP Endpoint Agent 15.7 MP2. However, the DLP Endpoint Agent package must be generated using DLP Enforce Server 15.7 MP2.
