I posted this question, and subsequently a partial cause of the  
behavior in the TeXShop forum. Herb asked me to report to the list.  
The original observation is:

While waiting for some suggestions, I went digging on my own. It  
appears that the problem is an interaction between xelatex and Cocoa  
PDFKit. I wrote a short sample and ran it through xelatex and  
pdflatex. The bookmarks from the latter consistently work, but not  
the latter. The sample is:


Then I built the PDFViewer sample code from the Developer directory,  
and set a breakpoint where the outline item is selected. The reason  
that the bookmarks didn't work is because the call to the  
"destination" method of PDFOutline for the item selected returns  
NULL. I looked through the PDFKit docs and the mailing list and  
couldn't find an explanation for it. My best guess right now is that  
there is a bug in PDFKit in Tiger.
