Additional notes

  • Big Sur is supported by SEP 14.3 RU1 only when running on Intel chip.
    SEP 14.3 RU2, ETA in Spring of 2021, will support Apple Silicon (the Apple M series chip).
  • Neither Apple or Symantec support macOS 10.12.x or older
  • Mac OS X 64-bit mode is supported.
  • PowerPC processors are not supported as of version 12.1.x.
  • As of version 12.1.2, case-sensitive formatted volumes are supported.
  • Remove legacy Symantec AntiVirus (SAV) for Mac installations before installing Symantec Endpoint Protection. 
    See Remove Symantec software for Mac using RemoveSymantecMacFiles.
  • Mac clients for Symantec Endpoint Protection Cloud do not support Mac OS X 10.11 (El Capitan).
  • As of macOS 10.13, you must authorize the Symantec Endpoint Protection kernel extension after installation for Symantec Endpoint Protection to fully function. You are prompted during the client installation to do it if needed. If you do not do it during the client installation, go to System Preferences > Security & Privacy, and click Allow. Neither Symantec Endpoint Protection nor the Mac operating system continue to remind you that you must do this.
    You only need to authorize the kernel extension once during the life of the computer's operating system. If you uninstall and reinstall the client, you don't need to reauthorize the kernel extension. If you have Symantec Endpoint Protection 14 and then upgrade to macOS 10.13, you don't need to reauthorize the kernel extension. However, if you reinstall the operating system, you need to reauthorize the kernel extension.
    See About authorizing kernel extensions for Symantec Endpoint Protection for macOS 10.13.
  • Kext notarization was added in macOS 10.14.5. If you install a client version earlier than 14.2 RU1 (refresh) on macOS 10.14.5, or upgrade the operating system to macOS 10.14.5 with an earlier version of Symantec Endpoint Protection already installed, you may experience issues. 
    See Endpoint Protection 14.2 RU1 and kext notarization for macOS 10.14.5.

Intrusion Prevention

Intrusion Prevention (IPS) is available in version 12.1.4 and later.

Device Control

Device Control is available in version 14 and later. You can only enable Device Control for managed clients.

Firewall

Mac client versions earlier than 14.2 do not include a firewall.

IPS was introduced in version 12.1.4, but broader firewall support (e.g. traffic rules) and feature parity with the Windows product was not included until version 14.2 and later. This firewall is only available to managed clients.

Web Traffic Redirection

14.2 introduced basic PAC file management to the SEP for Mac client.

14.2 RU1 expanded this to support full Web Traffic Redirection, including seamless identification with Web Security Service. Note: 14.2 RU1 MP1, or newer, is recommended for WTR on macOS due to numerous fixes introduced with that release.

Symantec Endpoint Protection 12.1.x

The End of Standard Support Life fell on April 3, 2019. See End of Support Life for Endpoint Protection 12.x.

Symantec Endpoint Protection 11.x

Support for version 11.x ended on January 5, 2015. See FAQ: Upgrading Symantec Endpoint Protection 11.x to version 12.1.x.
