Mauled by the Mac OS Lion.
The OS upgrade took my primary account and converted it (somehow?) into a GROUP. The files for this account are present, but it isn't really an account anymore so I can't log into it. It's a very odd state to be in. Current state is this: created new account with Admin privileges. Am considering options: attempt a manual migration? Attempt to migrate a user from an old backup (does that even work?)
Thanks for nothin', Steve.
application of chown -R, aggressive copying and typing in lots of passwords, i've restored sync, omnifocus, dropbox, itunes....
lesson learned: the cloud can't get here a minute too soon. the parts that were painless were all cloud-restore experiences. Everything that was connected to my laptop was a total pain in the backside.
