Love iMessage on your iPhone? You'll love it on your Mac, too. Messages lets you send unlimited messages to anyone on a Mac, iOS device, or Apple Watch. Your messages can include photos, videos, documents, audio, and contacts, and you can even see when your message has been delivered and when someone’s typing a reply. With end-to-end encryption, your iMessage conversations stay safe and private. And those green SMS text messages on your iPhone? They’re also on your Mac. Because all your conversations are available across your devices, you can start a conversation on your iPhone and pick it up on your Mac.
