Hi, this might be of use to some of you.
I’ve got an applescript that (using Acrobat) crops imposed printer proof pdf files so I can print them on the desktop printer for checking. Anyway, when I ran it just now it failed because 'Printer Setup Utility ’ could not be found … It seems it wasn’t included in Mavericks. Before Mavericks it was located in HD/System/library/CoreServices/
Anyway, all I had to do was restore it from Time Machine, and my script runs now!
