Most of the time when I login or open the lid my macbook bro mid 2012, the webcam light turns on for about a second and then turns off. Is there anything I should be worried about like a virus using my webcam to take photos of me from my computer or something?

    Possibly, but the webcam can also be used without the light on... As per Dutch government, put a sticker on it if you don't use it on purpose. – Rob Mar 28 '14 at 14:09

It's possible you have installed, or someone else has installed, a system utility to capture the image from the iSight when opened. This is often something an anti-theft application might do, in order to track down the user of a stolen laptop.

One combination of utilities that can do this sort of thing is "sleepwatcher"

You might check to see if there is a file at


or an invisible file in your home directory called


If so, sleepwatcher is installed.

This happened to me and I found it was because photobooth was open and trying to access the camera everytime it woke. I'd make sure it's closed.
