Set Up iMessage on Mac: Sync Your Messages

iMessage is Apple's popular messaging service that lets you send free messages, photos and videos to other Apple users. A big advantage of iMessage is that you can use it not only on your iPhone, but also on your Mac. In this article we explain step by step how to set up iMessage on your Mac and sync messages across all your devices.

Why use iMessage on your Mac?

Having iMessage on your Mac offers many advantages. You can type messages on a full keyboard, which is much faster than on your phone. You no longer have to reach for your phone while you're working on your computer. All attachments and photos are immediately available on your Mac for further editing.

What's more, with iMessage on your Mac you can also receive and send SMS text messages when your iPhone is nearby. This means you can also communicate with people who don't have an Apple device, all from your Mac.

Requirements for iMessage on Mac

To use iMessage on your Mac, you need to meet a few requirements. You need an Apple ID that you're signed in with on your Mac. Your Mac must run a recent version of macOS. The Messages app comes preinstalled on every Mac.

For SMS forwarding you also need an iPhone with iOS 8.1 or later, signed in with the same Apple ID. Your iPhone must be nearby and connected to the same Wi-Fi network, or you must have iCloud for Messages turned on.

Activating iMessage on Mac

Step 1: Open the Messages app

Open the Messages app on your Mac. You'll find it in the Applications folder, or through Spotlight by pressing Command-Space and typing 'Messages'. The first time you open the app, you're asked to sign in.

Step 2: Sign in with your Apple ID

Enter your Apple ID and password. Use the same Apple ID as on your iPhone to sync messages. If you have two-factor authentication turned on, you also need to enter the verification code that is sent to your other devices.

Step 3: Set up phone number and email

After signing in, you can choose at which addresses you can be reached for iMessage. Go to Messages in the menu bar and click Preferences. Click the iMessage tab. Here you'll see your phone number and the email addresses linked to your Apple ID.

Check the addresses you want to use. We recommend checking both your phone number and your primary email address. Under 'Start new conversations from' you can choose which address is used by default.

Syncing messages via iCloud

To keep all your messages synced across all devices, you can turn on Messages in iCloud. This makes sure your message history is stored in iCloud and is available on all your devices.

On your Mac

Go to Messages, then Preferences, and click iMessage. Check the option 'Enable Messages in iCloud'. Your messages are now synced with iCloud.

On your iPhone

Go to Settings, tap your name at the top, and then iCloud. Scroll down and turn on the switch next to Messages. Your existing messages are now uploaded to iCloud.

Syncing can take a while if you have a lot of messages. Make sure both devices are connected to Wi-Fi during this process.

Forwarding SMS messages to your Mac

Besides iMessage, you can also receive and send regular SMS text messages on your Mac. This works through your iPhone, which acts as a relay.

Turning on SMS forwarding

On your iPhone, go to Settings, tap Messages, and then Text Message Forwarding. Here you'll see a list of devices signed in with the same Apple ID. Turn on the switch next to your Mac.

A verification code appears on your Mac. Enter this code on your iPhone to confirm the link. You can now receive and send SMS messages on your Mac.

Handy features in Messages on Mac

Tapbacks and effects

Just like on your iPhone, you can react with Tapbacks on your Mac. Hold down Control and click a message to add a heart, thumbs up or another reaction. You can also send message effects such as confetti or balloons by holding down Command and clicking the send button.

Sending attachments

Drag files straight into a conversation to send them. Or click the Apps icon next to the text field for extra options such as photos, stickers and more.

Searching messages

Use the search field at the top of the app to search through all your messages. You can search by name, word or even by type of content, such as photos or links.

Troubleshooting

If iMessage isn't working on your Mac, first check your internet connection. Go to Messages, Preferences, iMessage and check that you're signed in. Try signing out and back in if the problems persist.

If messages aren't syncing, check that Messages in iCloud is turned on on all devices. Make sure you're signed in with the same Apple ID everywhere.

Privacy and security

iMessage messages are end-to-end encrypted, which means only you and the recipient can read the messages. Apple cannot read the content. If you use Messages in iCloud, your messages are also stored encrypted in the cloud.

You can set messages to be deleted automatically after a certain time. To do this, go to Messages, Preferences, General and set how long messages should be kept.

Conclusion

Setting up iMessage on your Mac is easy and very convenient. With message syncing via iCloud, you always have access to all your conversations, no matter which device you use. Whether you want to type a long message or simply don't want to reach for your phone while you work, iMessage on Mac makes communication seamless.
