Apple – Support – Discussions – Disable iSight ….
1. Use Parental Controls
2. You do not tell us which Mac and Mac OS you are using.
If you have a built-in iSight and have removed the “QuickTimeUSBVDCDIgitizer.component” file from your computer’s HardDriveName > System > Library > QuickTime folder, restart your Mac and try again. Your built-in iSight should no longer work with any app.
If you are using external (Firewire) iSight, you need only unplug the Firewire cable to disable your iSight. (Thanks EZ Jim)
Watchmac 1.6 bloo7. ”Watchmac monitors your Mac for possible infringements. For instance, when someone tries to unlock your screensaver but fails to enter the correct password, Watchmac will record this event and can even take pictures using the built-in (or an externally connected iSight).”
RickieV found his own answer. “Close your macbook – it goes to sleep, make sure the power adaptor is plugged in.
wait 5 seconds,
with a wire or wireless keyboard press any keys and wait about 5 sec. The Mac should wake up and show the monitor screen on the external monitor.
After 1 minute, you could open the Macbook Pro monitor cover and the monitor should stay turned off. Allowing you to use the iSight cam with the monitor off and saving the life of the monitor.
Hope this helps other people who’s been trying to do this too.”
