I vaguely recall seeing something about this a while back, and the
solution involved finding and removing TeXShop's configuration file,
which had become corrupted and easn't being removed or overwritten by a
reinstallation. But I can't find the thread.
FWIW, some entries in the MacTeX FAQ might help here:
"QT.02: TeXShop refuses to start, or behaves strangely. Or, for example, you
get the message:
"/usr/texbin/altpdflatex does not exist.
Perhaps TeX Live was not installed or was removed during a
AT.02: There may be a damaged TeXShop preferences file. Quit TeXShop,
and reboot your machine. Then before starting TeXShop again,
move the file
to your desktop. Then start TeXShop. If this fixes the problem,
reset your preferences as desired. If not, put the old plist file
back to restore your old preferences.
Make sure you are using the latest version of TeXShop
QT.03: TeXShop complains of a damaged Macros file when it starts.
AT.03: There may be a damaged Macros folder in TeXShop's configuration
files. Quit TeXShop, move the Macros folder
to the desktop, and restart TeXShop. It will create a new
Macros folder with a working Macros file.
Also, according to:
if you get error messages like "Library/TeX/... does not exist", you may
have a path problem in your preferences: "The correct path is
/Library/TeX/texbin not Library/TeX/texbin/pdflatex"
Emil, if you fix the problem, do post the answer to us so that it
can help others in the same boat in the future.
