I do not get a lot of incoming calls now that I have my mobile set to send unknown numbers straight to voicemail, but I noticed that the calls that do come through to me also trigger FaceTime (I think that is what it is called) on my MacBook. My 5s never did this. Is there a way to stop FaceTime lighting up on my Mac every time a known caller comes in on my mobile? I think FaceTime is great, but I have very few people with whom I would care to do calls with on it. Thanks!
