My family runs entirely on Macs, and I've recently ordered one of the new iMacs to replace my old black MacBook. I'm giving it to my mom to replace her MacBookPro, which she is giving to my dad to replace his Mac mini, which he is giving to my younger brother. I know how I'm going to transfer everybody's data over to their new computers, but I'm not sure on one thing. Both of my parents have email accounts with our local ISP and have had them for years - neither one has any idea what the password to their accounts are. Of course, they can still access their emails, but that's only because the passwords have been stored in Mail.app since they got their computers. my question is if I copy a specific file or folder over to their new computers, can I retain the account setup? Meaning that when they open Mail.app, the same account will be in place, ready to use? Or do they need to get in contact with our ISP to retrieve their passwords? Thanks for any help. By the way - I know how to copy existing email messages over - that isn't a problem. Just the accounts themselves.
