A new bug in Apple’s FaceTime app that allowed for possible spying has the Internet in an uproar. Mac expert Thomas Reed swoops in as the voice of reason. Apple has disabled the service that allowed this bug to work. The bug relied on a feature of iOS 12.1 and macOS 10.14.1 called Group FaceTime. If you are using an older version of iOS or Mac, you have nothing to fear. Apple will undoubtedly release iOS and Mac updates with a fix for this bug.”]
