First, go to Applications and click Utilities . Next, open the Terminal application . Or you can type the Terminal keyword into Spotlight to open Terminal.

launchctl unload -w /System/Library/LaunchAgents/com.apple.rcd.plist

Inside:

1. Launchctl : Mac application manages services running in the background.
