FaceTime
Use FaceTime to make video and audio calls from your Mac to a friend or a group of friends.
Ask Siri. Say something like: “Make a FaceTime call to Sharon.”
Make a FaceTime call. Use the built-in FaceTime HD camera on your Mac to make FaceTime video calls. Click New FaceTime, enter a name, phone number, or email address for the person you want to call, then click FaceTime. If it’s not convenient to make a video call, click the pop-up menu and select FaceTime Audio to make an audio-only call. When you receive a FaceTime invitation, you can choose to join with video or just audio.
Tip: While a video call is in progress, you can drag the small picture-in-picture window to any corner of the FaceTime window.
Use FaceTime with a group.You can connect with up to 32 people in a group call. Make a unique link to share with a group. Click Create Link. Copy the link to your Clipboard or share directly with friends in Messages or Mail. You can now use a link to join FaceTime calls on non-Apple devices.
Tip: Add a FaceTime link to a Calendar event to schedule a call for later.
Sign language recognition and Live Captions. FaceTime detects when a participant is using sign language and makes the person prominent in a Group FaceTime call. FaceTime Live Captions detect what’s said and present real-time captions for the active speaker.
Watch and listen together. Use SharePlay to watch and listen together on Mac. You can also share your screen during a FaceTime call. Click the SharePlay icon 
to start. See Share experiences with SharePlay.
Note: Some apps that support SharePlay require a subscription to participate. Not all features and content are available in all countries or regions.
Make a phone call. If you have an iPhone with iOS 8 or later, make phone calls from your Mac using FaceTime. Just make sure your Mac and iPhone are signed in with the same Apple ID account and that both have the feature turned on. (On your Mac, open FaceTime, choose FaceTime > Preferences, then select “Calls from iPhone.”)
Note: Your MacBook Pro and iPhone must be connected to the internet and the same Wi-Fi network to make or receive calls on your Mac.
Use the Touch Bar on your 13-inch MacBook Pro. Start typing a contact’s name, then tap your selection. On the Touch Bar, choose Audio or Video for the type of call you want to make.
