New iMac Messaging Not Synching

On my new iMac the messaging app is not synching all messages that are available on iPhone and iPad and old iMac. I have closed the app and reopened it with the same result. It only shows one addressed message that actually had been deleted and does not show up on messages on the other devices.

Hi there Vaccaro81,


Thanks for joining us in Apple Support Communities! We understand messages aren't syncing, and you're asking how to view the messages from your other devices on your new iMac. We're glad you're here, and we can provide some guidance.


To start, you'll want to be sure you signed into Messages with the same Apple ID you use on your other devices. Learn more about setting up Messages on your Mac here:

Next, in order to keep your messages updated on all your devices, you'll want to check to be sure you're using Messages in iCloud on your Mac. Have a look at the 'Turn on Messages in iCloud' section in this link for more information:


Use Messages in iCloud on Mac


Before turning on Messages in iCloud on your Mac, you may want to double-check your other devices to be sure they're using Messages in iCloud, too. Find out how here:
