Hello everyone, a few minutes ago I was on facebook with my macbook pro (using Chrome) and I realised that the iSight green led was on. So I checked if my Facetime or Skype app was running, but it was not. So I thought, maybe I called someone accidentally on Facebook, but this was not the case too. Only running apps were Outlook, Word, Powerpoint and Chrome. But after I closed the tab of Facebook, the green light turned off. So I would to ask you, what can be possible the reason of that green light? Hope you can help me.
