Install / Upgrade McAfee ENS on Mac OS

Windows Admins usually have hard time managing MacOS systems. Are you looking to Upgrade or Install McAfee ENS (EndPoint Security) on Mac? If yes then this post will helps you. Here will outline the steps to Upgrade McAfee ENS from 10.5.x to 10.6.x version. But this method well suitable for fresh Installation too.

There are GUI and CLI based Installation methods. But you are free to choose your preferred method.

Note: The products discussed here are of enterprise types. Since you need to have valid grant number to download the products. And the guide provided here suitable for McAfee ePO environments.

Step 1 – Upgrade or Install McAfee ENS on Mac

Note: These steps are applicable for both new and upgrade Installation.

Download McAfee ENS packages (.dmg) from McAfee products download page. For Instance assume ENS version 10.6.5 to demo here.

Method 1 – GUI Installation

  1. Execute “McAfee-Endpoint-Security-for-Mac-10.6.5-RTW-standalone-115.dmg”
  2. Then the Installer dialog box let you choose ENS modules to be Installed. ENS modules are,
    • ENE Threat Prevention
    • ENS Firewall
    • ENS Webcontrol
  3. Once choose the module follow on screen Instruction. Then wait for it to show “Installation completed” popup message.
  4. Proceed to Step2 to enable ENS services for first time.

Method 2 – CLI Installation

This is my favorite option. Because its simple and silent type Installation.

  1. Additional Install script needs to be downloaded for CLI Installation. Download appropriate deployer script from KB84772
  • For ENS version 10.6.5 and later: Download product_deployment_2.0.zip
  • For ENS version 10.6.4 and earlier: Download product_deployment_1.0.zip
  1. Secondly extract the downloaded archive. Then move deployer script to location where ENS package (.dmg) exist. Lets assume both are in Desktop itself
unzip -d ~/Desktop/ product_deployment_2.0.zip
$cd ~/Desktop/
  1. Now do execute the script for Installation to happen. This is same in case of upgrading existing product to newer version.
--Syntax--
 $sudo sh product_deployment.sh <<ENS module code names>>

--Module codes--
TP - ENS Threat prevention
FW - ENS Firewall
Wc - ENS Web Control

For example, this command Installs ENS Threat prevention and Firewall modules silently.

$sudo sh product_deployment.sh TP FW

If Installation succeeds, message similar to below appears on terminal window.

installer: Installing at base path /
installer: The install was successful.
"disk2" unmounted.
"disk2" ejected.

Once completed proceed to Step2 to enable ENS services for first time.

Step 2 – User consent to Load ENS kernel extensions

Note: You might not need for this step when upgrading existing products

What is SKEL?

Ever since macOS High Sierra (10.13) Apple Introduced new security feature called Secure Kernel Extension Loading (SKEL). As this feature requires end-user consent to load any third-party kernel extensions that are installed after the installation of macOS.

Because of SKEL, the kernel extensions of ENSM Threat Prevention – on-access scan, Firewall, and Self Protection are not allowed to load without end-user consent. Hence user must manually authorize McAfee ENS kernel extensions. But this is only needed for very first time after a fresh Installation.

Until user provides consent McAfee ENS remains disabled. So to do that please follow these steps.

  • After Installation finished (from Step1) wait for 10 mins.
  • Since ENS kernel extensions will start loading automatically after 10mins of Installation.
  • Due to which end user sees a McAfee Alert that prompts whether to allow the McAfee kernel extensions, from the Security & Privacy System Preferences pane.
    Note: McAfee Alert re-appears every 30 minutes, until the user provides consent.

    • As a result McAfee kernel extensions will get loaded

  • Further on next policy enforcement, McAfee ENS services starts operating normally as per policy.

Step 3 – Allow full disk access to ENS Threat Prevention (TP)

Ever since Mac Mojave version (10.14), full disk access must be granted exclusively for services. In our case McAfee ENS services needs to be granted with full disk access. Otherwise ENS virus scanner will not be able to scan user protected files.

To provide full disk access,

  • Navigate to Apple menu => System Preferences => Security & Privacy => Privacy tab => Choose “Full disk access” from left side menu list => At bottom left corner click on lock symbol and enter password => Click “Unlock
