Tranferring mails from a Mac Mini to a Macbook Pro 2019
I'm actually using a Mac Mini late 2012 running High Sierra 10.13.6 and recently I got a Macbook Pro 2019 running Monterey 12.4. I would like to transfer only the emails and Mailboxes I've created in High Sierra to the new Mail installed in the Macbook Pro. I have tried to do it using Time Machine but I didn't find how. How can I solve this?
