I just set up my new iMac, migrated everything from my MacBook Pro, and everything works EXCEPT Mail. I have configured my MobileMe settings to synch everything, and online, everything is there: contacts, all old email, etc... but Mail doesn't show any of this stuff, nor will it retrieve or synch any of my email accounts. Also, I have to Force Quit it everytime to exit the program. Could this be something with the Preferences file, or .plist file? Really is annoying.
