If your app is already installed by the systems way of installing things[TM], 
it is a bad idea to overwrite these files with your own ones. It will confuse 
the package-management and therefor confuse the user. Worst case is that the 
system becomes impossible to update system-wide. I don't think you want your 
app to be the reason for such a thing...

I believe your reason of auto-updating your app is to let the users always 
have the latest version. But to deal with this from the app-developers side is 
both complicated and time-consuming (at least on linux and unix, which mac osx 
is). A better solution would be to work closely with the packagers and let 
them do the necessary things. They know about dependencies and version 
conflicts and updating rules...

If you still want your app to update itself, you should really use the 
platforms deployment tools to do so. This has the benefit that is already 
provides the external updater-app you would otherwise have to write your own.

Have a nice day,

Arnold
