Products

Issue/Introduction

High CPU use may be experienced on some macOS 10.15.x machines running the 14.2 RU2 release of Symantec Endpoint Protection (SEP). The process involved is the new com.symantec.mes.systemextension.

Environment

macOS 10.15.x
SEP 14.2 RU2

Cause

Due to changes made in macOS 10.15, scan operations with autoprotect were happening unnecessarily.

Resolution

This is resolved in Symantec Endpoint Protection version 14.2 RU2 MP1 build b5576 and is available via the Broadcom Download Center


Please note that 14.2 RU2 MP1 b5576 is a Mac only build. All other build types within the download will still be the base 14.2 RU2 MP1 build.
