What you are trying to do is open the display assembly to remove the camera.
Sadly, all of the current MacBook, MacBook Air & MacBook Pro have displays which are very hard to open. I would recommend you get an older Unibody model (13 or 15”) as you’ll have a much easier time.
I would recommend you place a black and then yellow tape across the lens. I’ve done hundreds, lots of fun! :-{
The yellow tape is our standard so anyone can validate it’s been altered by looking into the cameras location. We did not remove the camera just prevent it from working.
