I had this problem on a unibody MacBook. The solution was installing the 10.6.2 combo update.

The replacement upper case cracks aren't harmful to the computer, however, they look worse than a mouth full of missing teeth. My suggestion to you, is to call Apple and ask them for a replacement. There is a somewhat unknown replacement program for the case chips and cracks. Alternatively, you could always buy the case part from ifixit. ;-)

I’d be careful about using a vacuum cleaner on the inside of the computer as it can cause static discharge and zap your components.

Thanks for this guide! It was a snap to get the computer apart and back together again.
