So as the title says, when a call comes in to my iPhone my rMBP starts ringing before the iPhone. It's a pleasant sound but this only started about a week ago. The first time it happened I was going nuts trying to figure out where the sound was coming from. After the third call I realized it was incoming calls that were doing this. I called my iPhone from the house phone and sure enough my rMBP started ringing before the iPhone. What is this? Has anyone experienced this?
