Luckily, since Macs are Unix based, the average user has a lot more control than on a Windows computer. So here's how to remove Endpoint Security...first you need to open the Terminal app and run the following command...
sudo /usr/local/McAfee/uninstall EPM
The above will ask you to enter your password and if everything is successful, the following output is produced...
Firewall uninstalled successfully
ThreatPrevention uninstalled successfully
WebControl uninstalled successfully
Product has been uninstalled successfully
That's not quite the end though. The agent services also require uninstallation. For this, there is a separate script and command to run...
The following output should be produced...
Stopping agent service
McAfee compat service is already running.
Stopping McAfee compat services... [OK]
McAfee agent service is already running.
Stopping McAfee Agent services... [OK]
McAfee common service is already running.
Stopping McAfee common services... [OK]
Removing agent configuration information
Deleting user (mfe) & group (mfe)
...and finally unload the launch agents...
launchctl unload -F /Library/LaunchAgents/com.mcafee.*
This completely removes Endpoint Security. As a word of caution - I do not recommend doing this as a permanent solution, especially if your corporate policy requires this software to be installed. However, as I said at the start of this article - removing it temporarily to get through intensive tasks is ok in my view (just remember to reinstall it!)
