At the time the user requests I initiate an NSTask and deploy:

[unzipTask setArguments:[NSArray arrayWithObjects:@"-x",@"-
k",sourcePath,targetPath,nil]];
The problem is that the deployed Helper file has the 'X' icon and
displays the "application is damaged.." message.
If I take the Helper.zip file from the 'contents' and manually
double click it then the decompression works fine….
I'm so close and just I can't see what's stopping this deployment.
Is there a ditto flag I need to set that I'm not seeing?
I have seen this problem before in a similar situation. At the time,
my diagnosis was that the Finder was seeing the top-level .app dir
created, and it looked inside for a Contents/Info.plist etc. before
the de-archiving was complete. As a result, Finder's first
impression is that the app is incomplete (damaged), and it then takes
some work to convince Finder to reverse that opinion. IIRC, I had to
trick Finder.
One way was to de-archive to a folder not named "Something.app", but
instead just use "Something". Then after the de-archiving finished,
rename the dir to "YourApp.app". I even used a temp name that starts
with ".", which Finder won't show.
Another way is to trick Finder into re-reading the bundle's contents,
by modifying the top-level ".app" folder's mod-date. I did this by
creating and then removing a temp file, but you could also set mod-
date directly. I just found it easier to create & remove a file,
because this was all done in a shell script.
I don't recall which one worked, or worked better, or on which OS
versions, so I suggest running a few experiments.
You could also probably fix the problem using the Launch Services
API, or running the lsregister command. If you'd rather avoid kluges
or magic tricks.
