Do you want to change the caller ID that others see when you FaceTime them from your Mac? This is possible and in fact, pretty easy to do.
If you use FaceTime on multiple devices like your iPhone, iPad, and Mac, chances are, it uses your phone number by default as your caller ID. Now, if you’re a privacy buff or you’re trying to make a FaceTime call for work purposes, you may not want to give away your personal phone number like that. To avoid this, you’ll need to change your FaceTime caller ID to your email address.
