I'm recovering data from a corrupt OS 10.7.4 drive in a '09 MacBook, using a Mac Pro running OS 10.6.8 with Data Rescue 3. Most of the user data was easy to find and recover but I'm unsure of what (and where to find) Mail data I will need to restore four Mail accounts, complete with mailboxes and smart mailboxes, in four user accounts. Also, I'd like to recover serial numbers, registration info and setup preferences for the applications. Where would these be found? Possible to just copy over applications and related files? Trying to make sure I don't miss anything. Thanks in advance for any help.
