xul updater for mac

[pat]

I've recently added xul's auto update functionality to an xul
application that runs on linux, mac and win. All works fine in linux
and win but on mac the update fails.

The mac version will download, verify the partial mar and ask the user
to restart the app to apply the patch. When the user clicks restart
the app shuts down but does not restart. if the user then starts the
app they get a dialog box that says the patch failed, click here to
download and install the complete patch. The app successfully
downloads and verifies the complete mar but once again fails to apply
it after the user clicks restart.

Before i spend to much time digging into this does anyone have any
suggestions as to why this might be failing, more specifically, is
there anything that should be done differently for a mac patch
compared to a linux patch (the patch's directory structure matches the
app's exactly)?

Thanks for any help.

resolved, not sure what the issue was. I had been using an xul
framework for the mac that I grabbed from https://developer.mozilla.org/en/XULRunner.
The app worked fine except for the problem noted above. I grabbed Mark
Finkle's xul explorer (https://developer.mozilla.org/en/XUL_Explorer)
and plugged my app into it's framework (version 1.9.0.3) and
everything worked fine including the updates. As a bonus i ended up
with a smaller (8.5M vs 15M), quicker starting app.
