All of a sudden, when I turn on/log in on my Macs that are running OS X Mavericks, I am getting a window that asks me to input the password for FaceTime. This really started driving me crazy, as I don’t use FaceTime, and I don’t even have a camera connected to my Mac Pro.
To stop this from happening, I just turned FaceTime off. To do this, open a new finder window, and then open your Applications folder. Now click/open FaceTime. Click and drag down the “FaceTime” menu option and simply select “Turn FaceTime Off”.
