[Mac OS X TeX] atchange

<x-flowed ISO-8859-1>I took Phillippe  Lelédy's suggestion and downloaded the perl script 
atchange.  I ran it like this

atchange mydoc.pdf open mydoc.pdf

hoping that that would make Acrobat Reader show all changes to the file 
mydoc.pdf.   Unfortunately, this doesn't work: it turns out that if 
Acrobat already has mydoc.pdf open, doing another 'open' won't make it 
reload the latest version of mydoc.pdf; it just keeps displaying the 
out-of-date version it has in memory.

Does anyone have a way to work around this?  One thing I thought of was 
opening mydoc.pdf in a web browser with the PDF plugin and somehow 
getting atchange to tell the web browser to "refresh"; but then I 
remembered that there is no PDF plugin for OS X---one of the biggest 
annoyances for me; my desktop keeps filling up with downloaded pdfs.  
(Or am I wrong about this?  Have other people been able to view PDF's 
with their browsers?)
