Note that both iMessages and SMS/MMS are included as part of Messages in iCloud.Īs a bonus, just like iCloud Photo Library, your messages will no longer be backed up as part of your daily iCloud Backup. Once the merge/sync is complete, if you delete a message in one location, it will be deleted from all your devices. This feature will upload all the messages from each of your devices to iCloud, and merge them with messages uploaded from other devices.įrom there, each device will only keep a cached copy of recent conversations, and download additional messages from iCloud whenever you try to view them.

On macOS, open the Messages app, then go to Messages → Preferences… → Accounts → iMessage and check Enable Messages in iCloud. On iOS, you enable this feature by toggling Messages under Settings → General → → iCloud.

Starting with iOS 11.4 and macOS 10.13.5 High Sierra, Messages in iCloud lets your messages sync across devices over iCloud.
