Apologies for the newbie question, but I did some searches and didn't find the answers I'm looking for. I have a 2012 macbook pro mountain lion and have been using Mail as my email client. I have a new iMac on the way and want to copy/transfer the email over to the iMac. What is the best method to use? Use migration assistant? iCloud or copy files and transfer them using a usb drive or other means. If transferring via drive is the best method where exactly are the files I want located still getting the hang of OSX file arrangement versus Windows. thanks in advance.
