Programs which are intended to display .pdfs are supposed to honour  
the security bits in a .pdf --- since TeXshop and iTeXMac aren't  
specifically intended for displaying .pdfs, this has not been  
considered AFAIK.

.pdf security is pretty weak, and it's just a matter of toggling a  
check in xpdf and re-compiling it to get a version of it which'll  
bypass .pdf security.... so if you're wanting somehing really secure  
you should try something else, say one of the rights-managed ebook  
formats.
