Laugh HN: sudo rm -rf .fseventsd/ * (I whacked my HD)
New 32gb model MacBook Pro and I was setting it up today. Half paying attention while talking to my wife about her new Thinkpad and why it wasn't working and I ran:
sudo rm -rf .fseventsd/ *
and guess what happened?
Off to do a restore and wait hours for a 5.7gb download from Apple. I guess I can make my wife a nice date night dinner while I wait.
