Hello, I would apprechiate if someone could help me. On my 2011 Air i7 I am still running Lion and now want to upgrade to Yosemite. I need to copy all my stuff to an external harddisc, then I want to completely delete the Air and do the clean install. I figured how to get iTunes media copied, as well as iPhoto and other Documents. I only use iCloud for few Apps such as Safari, Contacts and Calendar. These data will be synced from iCloud so thats easy also. The thing I dont know is how to move my emails and all the settings eg. account data & setup to an external disc. Where can I find those email data and which destination do I need to copy them to Yosemite? Hoping for your help, cheers. PS: I got a Time Capsule as well, but never did such thing before, I am not sure when I after a clean install of Yosemite am able to transfer those emails from my Time Capsule backup? I want to avoid to restore the whole setting, I want to keep it as clean as possible.
