Hey Fincha,
you might want to package locally. Here's a sample mac os packaging
command (which you would need to execute from terminal):
Library/Application\ Support/Titanium/sdk/osx/1.2.0.RC4/tibuild.py -d
<output path> -t bundle -o osx <path to your TI Desktop project's root
directory>
More on this can be found over here as well:

Hope this helps,
Cheers
