I don't know what this means or if it's a bad sign... I had my mini turned off, then turned it on. This little flashing picture of the world popped up and flashed on the grey startup screen for about thirty seconds. Then, a folder icon with the finder icon on it popped up, and the file icon flashed back and forth between the finder icon and a question mark. After a second, OSX started up and ran perfectly. What in the world happened? What does it mean?
