Another possibility is that a tool path is incorrectly configured in TeXShop preferences. This can happen if you are using the fink teTeX distribution."

First... are you sure your not having Hard Disk problems?

In Terminal please run the five commands

which pdflatex

ls -alF /

ls -alF /usr

ls -alF /usr/local

ls -alF /usr/local/texlive

and let us know the results.

Good Luck,
