Messages in iCloud allows you to sync your iMessages through all your Apple devices with the use of your iCloud account.
When this feature was first announced, it wasn’t an exact syncing, although users got messages on all devices, but, deleting a conversation on one device did not necessarily delete it from the others. Furthermore, when you set up a new Apple device, your previous conversations will not appear on it. Messages in iCloud makes all these possible, however it means that your free 5GB memory on iCloud will be used up. But you can opt for the 50GB service, it’s $0.99 per month.
To set it up on iPhone or iPad,
- Update your iOS on either your iPhone or iPad to at least iOS 11.4.
- Open the Settings app and tap your name at the top.
- Select “iCloud”.
- Toggle “Messages” on.
You also have to do this on any other iOS device you own that you wish to sync with iMessages.
To set it up on your Mac,
- Update your macOS to at least High Sierra 10.13.5.
- Next, open the Messages app.
- Head over to Messages and then Preferences on the menu bar at the top-left corner of the screen.
- Click the”Accounts” tab.
- Select “Enable Messages in iCloud”.
When that’s done you’ll see a popup that will inform you your messages are syncing with your iCloud account. The amount of time this takes depends on the amount of messages you have.
