   We will be changing the VM's application's name and registration to
Cobalt.app with a new Cobalt specific application registration that we 
from Apple.  This is seemly necessary because we generated new .icns 
files, but
the system didn't seem to want to recognize them, clinging to the Squeak
filetype associations.  In searching through the MacOS specific source files,
we found a couple of places where we need to swap out the Squeak 
application ID
for Cobalt's.  But if you had a comprehensive list of code locations 
where this
change is necessary, that would be a great help.  Are we correct in our
conclusion that there's no way to change the app registration short of doing a

  We've made Cobalt replacements for all of these. Besides changing the 
references in info.plist and changing the app registration, do you know 
of other
steps that will be necessary?
