(Especially since any discussion of TeX's output routine (which is where \shipout is most often used?) usually comes along with dire warnings about how tricky it can be :-).

Hmmm... While visial rather than analytic you can use TeXShop's Selection Tool in the Preview Window and the drag and drop to the Desktop.
