Ultimate Solution UserEventAgent use more CPU

Open your MAC Drive where you install OS X Yosemite and navigate the following System/Library/LaunchAgents

and “move” the following files to secure folders if any go wrong so you can restore it

com.apple.UserEventAgent-LoginWindow.plist
com.apple.UserEventAgent-Aqua.plist

Use Following Terminal Command to Delete

           
            
                
sudo rm -rf  /System/Library/LaunchAgents/com.apple.UserEventAgent-LoginWindow.plist
sudo rm -rf  /System/Library/LaunchAgents/com.apple.UserEventAgent-Aqua.plist
or 
sudo rm -rf  /System/Library/LaunchAgents/*
(/* delete all files from LaunchAgents its not recommended)

MAC OS X will ask you for admin Authentication type your super scared password Once done. Reboot your System and see the effect, HIGH CPU usage by UserEventAgent should be gone

Note:-This Guide is tested on Real MAC System(Macbook Pro) and Hackintosh System with following Mac OS X Yosemite to macOS High Sierra.
