How to Disable the iSight Camera (6 Steps)

Go to the System folder on the computer's hard drive. Inside the System folder, go to the Library folder. Inside the Library folder, go to the QuickTime folder. Go to the 'directory' and locate the 'QuickTimeUSBVDCDigitizer.component' file.
Create a 'Temporary Backup iSight' folder onto your computer's hard drive.
Copy the 'QuickTimeUSBVDCDigitizer.component' file to the new backup folder.
Delete the file in the directory by moving it to the trash. Do not delete both files--otherwise, you will permanently not be able to access iSight.
Open a web-based software program (iChat, Skype, Adium) and test to ensure iSight is not accessible.
