My new iMac (7600 i5, 575, 512 GB SSD) arrived at the Apple store yesterday (9 days early!). I'll be picking it up tomorrow and getting it set up and my data moved from my 2011 iMac during the next few days. I've been reading about the pros and cons of clean install vs. Setup Assistant for the past several months and have pretty much decided on going with the Setup Assistant route and checking the Account, Files/Folders, and Preferences boxes but not checking the App box. Plan on using Ethernet connection to both machines on my local network. Total to move should be about 100 GB. I have only a handful of 3rd party apps and don't mind doing a new install of them. But I have a couple questions: After I move my existing Account Info to the new iMac, will the account still be useable on my old iMac? I would like to use the old one as a backup for a month or so until I'm sure the new one is working well. Am I correct in assuming that, if I leave the App box unchecked, the Apps associated with OS-X (Mail, Safari, Contacts, Calendar, etc.) will still get moved along with their data? For example, will all of my Mail mailbox data be moved to the new machine? Any other advice / concerns? Thanks !
