Need to install the Symantec Data Loss Prevention (DLP) agent in a macOS endpoint computer.
Macintosh endpoint single manual install or SMS install for many Macintosh endpoints.

Verify the Mac agent installation:
Open the Activity Monitor application (also in Utilities folder) and search for the edpa process. It should be up and running. The Activity Monitor displays processes running under the logged on user. The edpa process runs as root. Go to View in the activity monitor window and select "All Processes” to view edpa if you are not logged on as root user.
You can also confirm that agent was installed to the default directory: /Library/Manufacturer/Endpoint Agent
