I will be updating two Macs to 10.6 in the comming days and want to get prepared. If you want to do a fresh "Erase and Install" of 10.6, what would be the best way to transfer your emails, photos, documents, files, settings, iCal calendars, Network settings, etc. back into the new fresh install? One of my Macs has 10.4.11 (I am most concerned about this one) and the other 10.5. But the one with 10.5 does not really need any info transfered. I'm more concerned about my iMac with emails, photos, iCal calendars, documents and settings that I'd like to have back after a fresh install. I have emails on both Mail and Entourage 08'. I would like to retain all those emails and the email addresses and setting for both. I also have some network settings I did for my sons DS Lite and Wii that I'd rather not have to spend the time redoing. Of course all the Documents, Photos, and Files are backed up to an external HD so that is really not a problem, but if I could just easily transfer them back all the better. I've done some searching in the past about saving emails for both Mail and Entourage 08'. I followed the steps and have routinely saved what I think are the correct files for those to my external.
