Some computer users would like extended privacy for personal or professional concerns by disabling web-friendly video recording software. ISight is a webcam built into Macintosh computers and accessed through web software. Disabling iSight will prevent any web-based software seeking a camera to find iSight on the computer directory. How to Turn Off the iSight Camera on My MacBook. The iSight camera comes built into several models of iMac and MacBook Apple computer systems. As a configuration-free webcam, it works automatically with iChat, Photo Booth, and some third-party communication and capturing software. The iSight camera normally turns off. The ability to turn the camera on without the green light was only proven in pre-2008 laptops. No proof exists that you can do the same in post-2008 laptops. This question Are there privacy concerns with the Built-In iSight Camera and LED Indicator? Seems to agree that newer models you can't.
The built-in camera on your MacBook Pro is really useful for a variety of reasons. If you want to use popular apps like FaceTime and Skype, you'll be using your camera pretty often. The cameras on MacBooks are pretty high-quality and functional but are more designed for video streaming and video chats than for real photography.
Regardless of how you want to use your camera, you need to know how to turn it on and off. We talked about how to turn your camera on in another post so for this one, we will look at how to turn the camera off. This is another easy task but is good to learn so you know your camera is not turned on at times when you don't want it to be.
Why Turn Your Camera Off
There are a few obvious reasons to turn your camera off and there are also a few reasons you might not have thought of. Since it is so easy to do, turning off your camera after you use it is a simple habit to get into when operating your MacBook Pro. Sometimes, you might want to double-check that your camera is off but once you know the steps, it takes no time at all.
1. Privacy

Privacy is a big issue in today's world of technology. Having access to so much information at the click of a button is an amazing aspect of the modern world but it also comes with potential privacy risks. The idea of someone accessing your camera without you knowing is pretty terrifying and something nobody wants. It's not likely but it is possible that this could happen to you.
Hackers can potentially access your camera and spy on you if it's not turned off or disabled and there is also a chance that if you accidentally leave your camera on, anybody you were chatting with could see video of you when you aren't expecting it. These are both instances that violate privacy that are fixed when your camera is turned off.
2. Save Battery
The camera is an awesome feature of your MacBook Pro but it does eat up more power than other uses of your computer. This display on your MacBook is one of the most power-hungry elements and you use your display constantly when you are using your camera. Video calls or live-streaming can quickly go through your battery if you are not plugged into a power source.
In order to avoid unnecessary power use, there are a variety of things you can do but making sure your camera is off is an important one. You can definitely use your camera when you are running on battery power if you need or want to but you will want to make sure it is turned off completely afterwards.
3. Save Space
Another reason to turn your camera off is simply to save space. If you accidentally leave your camera on and it starts to take pictures or videos without you knowing, it can quickly eat up lots of space on your hard drive. Images and videos can use up a lot of memory and storage, so it's good to know that you aren't adding extra files unknowingly. Unwanted files are easy to delete but they are also easy to prevent in the first place.
How To Turn Off Camera
Now that you know the reasons for turning off your camera, let's take a look at how to actually do it.
One of the easiest ways to turn off the camera on your MacBook Pro is to simply close the app you are using that uses the camera. When you open up one of these apps to turn the camera on, a little green light appears to the right of the camera lens. When you close these apps, the little green light should disappear indicating that the camera is now turned off. Sometimes you might need to hit Command Q instead of just closing the tab to fully quit an application.
If you are really concerned about privacy you might want to take further steps to prevent your camera from turning on without you knowing. One of the easiest ways to do this is to simply cover your camera lens with a piece of dark tape.
This may sound weird but if anyone tries to access your camera, even if they succeed, they won't be able to see anything if the camera lens is covered up.
A real hacker could access your camera without the green light turning on so this might be a good idea if you are really worried about your personal security and privacy. It's an easy measure to prevent your camera from recording anything at all.
Additionally, there is not a current method to disabling your Mac's camera through the standard programs and functions included on the machine. You will need to download a 3rd party app to really disable your camera. One app that works well for this is called iSight Disabler and this program will turn off your camera completely so you don't have to worry about it turning on without you knowing it.

Final Thoughts
Turning off your built-in MacBook Camera is really easy. There are a few different ways to go about this task and depending on how thorough you want to be or how much of concern privacy is, you can decide which option is best for you.
Do you put tape over your MacBook's camera?
Have you ever wondered if someone might be illicitly staring back at you through your webcam; watching your every move; all without your knowledge? Cynics have known this for ages, but people who generally trust humanity might be surprised. Yes, there are voyeurs in the world with the turpitude to use your webcam as a gateway into your private life.
Think about it for a moment.
How would you really know if someone was watching you?
Almost every modern laptop has an integrated webcam. Some all-in-one desktop PCs even have them. My question is this: what is there to stop some truculent hacker from hijacking your webcam and discreetly spying on you?
The saying 'I know what you did last summer' isn't just the titular name of a bad Jennifer Love Hewitt movie. In fact, last summer, I broke the news about the Blackshades vulnerability and how it opened passage for hackers to take over webcams.
You might say,
Well, Vonnie I know when my webcam is on because the little green light glows green
But to that I would say:
If only it were that simple.
People spying on you through your webcam isn't just the stuff of science fiction or silly movies. It really happens.
In fact, the FBI has been doing it for years.
According to Marcus Thomas, former assistant director of the FBI's Operational Technology Division in Quantico, the FBI has been able to covertly activate webcams without trigging the light for several years.
Of course, this technique was chiefly used to capture high-profile criminals, usually involved in acts of terrorism; however, it's still scary to know that the FBI had the ability to commandeer your webcam.
So here's the thing: Apple deliberately designed the micro-controller that runs the integrated iSight webcams to use a 'hardware lock'. The lock forces the indicator light to glow whenever the camera is in use. The idea was to make it virtually impossible to turn the camera on without turning on the light.
Isight Camera Replacement Program
But the problem is that your Macbook is more than a webcam microprocessor tucked inside a laptop lid. There is a veritable maze of circuits and chips that comprises your computer and each component can become a potential attack vector for criminals activity.
Researchers at Johns Hopkins University have actually figured out how to reprogram the firmware that runs the iSight webcams so they can disable the light while using the camera. In December of 2013, Matthew Brocker and Stephen Checkoway published a 15 page whitepaper titled: iSeeYou: Disabling the MacBook Webcam Indicator LED. The paper delineates how Brocker and Checkoway's re-engineered the firmware that drives the iSight camera and brings to light (pun intended) how an attacker might do the same thing.
It's still unclear whether Apple's newest line of FaceTime HD cameras are susceptible to this vulnerability; however, my point is that you shouldn't assume that your camera is off just because it looks off.
That's why I want to show you two very inexpensive and quick methods to protect your privacy. We're going to disable the iSight webcam on your Mac.
Blocking the iSight webcam with tape
The easiest thing to do is to take a strip of scotch tap and tape it over the camera lens. This will occlude the possibility of someone getting a clear view of you. This is a really fast and cheap way to obscure the webcam; however, it's not very pretty and could leave behind a sticky residue. I doubt you want to do that.
A Post-it note folded on itself is a smart technique. You'll get privacy with reminders all thrown in one shot. You can cut a small square out of the sticky section of the Post-it note, slap it over the camera and be done with it.
The next best option is to find white electrical tape or a white shipping label with adhesive backing.
A hole puncher can pop-out a webcam blocker of the perfect size. Just slide the tape into the hole puncher, punch out the hole and neatly stick it over your circular webcam lens. You can even buy special black or white webcam covers for a few bucks or get fancy with something like a magnetic webcam shield.
Either option gets the job done.
If the idea of sticking something on your webcam or covering it up isn't very appealing, we can manually remove the software component that drives the iSight camera.

Either option gets the job done.
If the idea of sticking something on your webcam or covering it up isn't very appealing, we can manually remove the software component that drives the iSight camera.
Disabling iSight in Software
Check it out.
Press the Command + Shift + c to open the Computer in the Finder app.
Click through the Macintosh HD folder.
Go to System, Library and then Quicktime.
Inside the Quicktime folder is a file named:
https://softwareprograms.mystrikingly.com/blog/colocalizer-pro-6-0-specs. QuickTimeUSBVDCDigitizer.component
Select it and press Command + c to copy the file.
Next, press Command + Shift + n to create a new folder.
Name it 'iSight Webcam Backup' and then press Command + v to drop a copy of the component in your new folder.
Then you can delete the original QuickTimeUSBVDCDigitizer.component and your webcam should be disabled.
If that doesn't work, you can go into Parental Controls (Command + Shift 'parental controls') and click Disable built-in camera under the Other tab.
You can also pull off the same effect using the iSight Disabler script by Techslave. It makes your Mac blind for as long as you need.
Extract the .scpt file then press Command + Shift + c to open your Computer folder. We need to drop the .script file in Macintosh HD, Library, Scripts. Universal extractor linux.
Create a new folder (Command + Shift + n) called 'iSight Disabler' and drop the .scpt file in there.
Isight Camera Not Working
When you double click it the Apple Script Editor will show up revealing the guts of the script.
Don't panic. We don't need to know how it works but you can peruse the code if you want. Click the Play button or press Command + r to run the script. You'll get a notice about Disabling iSight.
and now the next time you pop open an application that relies on your webcam such as Skype or FaceTime HD, you'll see a friendly error warning you that no such camera exists!
One thing I should point out is that this isn't a fool proof method of protection because if an attacker manages to get on the inside of your computer he may also figure out a way to remove the iSight Disabler. But one thing is for sure: it will almost certainly make it harder for the bad guys to do their dirty deeds.
On a side note, I tested this in Mac OS X Yosemite and it works just fine.
Isight Camera Software
One more side note: although this disables the webcam it doesn't disable the Mic, so keep that in mind. Baixar power point.
To disable the Mic, you can press Command + Space, type 'sound' and drag the input volume slider all the way down to the left.
The Bottom Line
I don't know why Apple doesn't include a toggle switch to let users disable the camera. A physical button on the Macbook would be perfect; or even just an unobtrusive shutter that you could flip over the lens would probably suffice. But no… no no… instead, we have to wrangle custom scripts and do all kinds of funky hacks just to turn off the webcam!
Textlab 1 3 5 – a text transformation tool. How do you feel about this? Does it bother you that your webcam is always there with no off switch? Let me know in the comments. I'm curious.
