To disable FaceTime on a Mac, open the FaceTime app and select FaceTime Turn FaceTime Off. This particular bug allows a caller to hear audio and see the camera feed from their recipients even though they didn't pick up the call.
Exploiting this bug could allow a person to listen in to their target's private conversations without the target knowing, and all they would need to do is FaceTime them. In some cases, the bug can also show live video of the other person if they press a volume button to dismiss the call.
The bug emerged on Data Privacy Day when Apple Chief Executive Officer Tim Cook called for "action and reform for vital privacy protections". While the call is dialing, swipe up from the bottom of the screen, tap "Add Person", and add your own phone number.More news: Article 50 row as McDonnell says Labour could back Brexit delay plan

A rather major bug has been detected within the FaceTime feature on Apple products. I was able to get it to work on a variety of iOS devices ranging from a very new iPhone XS to a very beat-up iPhone 5, but all were running iOS 12.1 and above. And that could be a very, very, very disastrous bug (via 9to5Mac).
Now that FaceTime is disabled, callers will be unable to utilize this bug to listen and watch you without your permission through FaceTime.
Apple added multi-person FaceTime calling at the end of a year ago via a software update that was, in part, created to address previous software bugs. Otherwise, people cannot only listen in on what you are doing, but in some cases also see what you are doing. You can disable FaceTime on your iPhone by heading to Settings and toggle the FaceTime icon to gray.
