My IT department installed McAfee Endpoint Security on my Mac

My computer was purchased for me, so I can't whine about that, and I set it up and managed software personally. All was working beautifully, until IT came and ran a few scripts. Now my Mac is "remotely managed" and McAfee Endpoint Security is installed. About every 5-10 minutes my fans are running 100% and "McAfeeATP" process is running at >100% CPU usage. Apps and terminal commands hang, usually with a McAffee process running with top priority. I actually decided to wipe my computer and do a complete reinstall hoping to just remove McAfee (which apparently is deep down in the system and cannot really be "uninstalled") only to find out what "remotel managed" really means. All the software was just automatically reinstalled on my fresh Mac and I'm back to square one. What's frustrating is I have zero options enabled for the McAfee software. Its always on and I can't turn it off. If I force quit it just comes back. Why do IT departments think software like McAffee is so useful? Any small system protection it is providing is shadowed by the immense pressure and resource usage on the system. It must slow down the overall productivity and efficiency of every user... If anyone has any tips or system settings for how to manage or sequester this app I would be very grateful.

Re: My IT department installed McAfee Endpoint Security on my Mac

Hi kalinmiya68,

Looking at the problem description I assume that your Mac must be part of Active Directory system management group and is centrally controlled by IT administrators. In this case, even though you try to do modifications to the McAfee application locally, the changes will be wiped off when there is McAfee agent to server communication.

With regards to ATP process consuming 100% CPU we would need to check what applications are being run on your machine and then add exclusions accordingly. If you are administrator on your Mac, could you try to switch the machine to kext-less mode by following the instructions from below article and monitor the system performance and response.
