Old iMac died. Have external HDD with backup files. Running 10.8.2 on new iMac. Specs below. Am currently working on doing clean installs of all my software. Mail.App. Do not want to use Migration Assistant from external, unless simple way to just move old mail boxes and nothing else. Now comes the million dollar question. Would like to bring all my old mail boxes onto my new machine. Used to be simple, but things have changed. From my searches on the subject, seems ML hides them. Could someone please assist me with this? Your help will be greatly appreciated. Any further info required, just ask.
