Hi, My computer MacBook Pro crashed but I have a backup. My 'spare' (just calling it that for clarity) machine is the same model and has the same operating system already installed - El Capitan. Excuse the lengthy ask, process of drilling down to what is possible, if anything. I have searched and searched and tried many different things but nothing so far has worked. Question 1: Is there any way to copy, migrate, restore ONLY the Address Book Contacts and Emails, the draft emails are the most important (I am using MacMail) from the TimeMachine backup to the 'spare' machine? To complicate matters the MAIL on the TimeMachine backup is a hidden folder, I have tried to find and written script to 'show' it. But nada. If above is not possible: Question 2: Is there any way to open the mail on the TimeMachine backup and choose manually what I want to retrieve. (please note I am using a backup from the crashed computer so I can't use the convenient "enter TimeMachine" and scroll through because it only allows me to scroll through new email backups on the 'spare' replacement computer). OR Question 3: If I create another user name on the 'spare' computer with the same user name as on the backup TM user will that work? And how? I have tried a few trial and error ways but it's all error to date. I do have all my user passwords. If none of the above is possible: Question 4.: If I do a full restore or migrate (or ?) of all data on the TimeMachine backup to the 'spare' computer will it overwrite the information, settings etc. that are already on the 'spare' computer? Or is there a way to create partitions on the 'spare' computer that will keep the backup and 'spare' system separate but still allow me to choose what I want to keep and copy it over to be accessible on 'spare' Many thanks for any advice.
