How to Set Up Messages on Mac (& Sync Your iPhone Messages)

Last Updated:  |  Author:

Missing messages on your Mac? If you've just set up a new Mac and the Messages app is empty, or not showing your full message history, you're not alone.

Many users expect their iPhone messages to automatically appear on their Mac. But in reality, this only happens if your Messages and iCloud settings are configured correctly.

Why Are My Messages Missing on Mac?

When you first sign into the Messages app on a Mac, it will be empty. New messages you send and receive from that point forward will show up, but not your full message history.

To access all your historical chats, you'll need to enable "Messages in iCloud" on both your iPhone and Mac.

How to Sync iPhone Messages to Mac

To access all your existing iPhone messages on your Mac, you need to enable "Messages in iCloud" on both devices. This ensures your messages are stored in iCloud and kept in sync across all your devices, allowing your Mac to download your full message history.

Expert Tip: Before syncing, ensure that you back up your iPhone. This way, if anything goes wrong during syncing, you won't lose any messages.

  1. Enable iCloud Messages on your iPhone
    Open Settings, tap your Apple Account name, then go to iCloud > Messages in iCloud and turn on "Use on this iPhone".
