On a whim I decided to see what DW found out about the health of the file directory of my four day old laptop. I booted the rMBR of the repair partition and ran DW via terminal. DW reported that I needed to have it rebuild the directory, after giving it a score of 7. I was surprised that it needed a directory rebuild so soon. I have installed Office for Mac beta, Clean My Mac 3, and f.lux.
