Phone calls and text messages on your Mac
You can take calls—and make them—right from your iMac. You can also receive and send text messages.
Note: Internet and Wi-Fi connections are required in order to make or receive phone calls on your iMac.
Take or make a call. When someone calls your iPhone, click the notification that appears on your iMac screen and your iMac becomes a speakerphone. If you want to make a call, click a phone number in a Spotlight search or in an app such as FaceTime, Contacts, Safari, or Calendar. You need a nearby device (iPhone or iPad) with a cellular connection in order to make phone calls.
Send and receive messages. Use iMessage to send unlimited messages to friends who use Mac, iOS devices, iPadOS devices, and Apple Watch. Send and receive SMS or MMS text messages right from your iMac. When friends and family text you, you can respond with whichever device is closest. All messages appear on your iMac, iPhone, iPad, iPod touch, and Apple Watch. See Messages.
