FaceTime Isn’t Just for Video
If you don’t need a video call but still want a fast conversation over your Mac, audio calls work great. Just head into FaceTime, choose a person to contact, and select Audio instead of Video. This can help save data for low bandwidth situations, and FaceTime has a great audio codec, so sound quality should be superb no matter who you are calling. You can also switch an audio call to a video call whenever you want to.
