[MacRuby-devel] Keep getting signature error on submission to mac app store

There may be a better way to do this, or it may be a bug, but I found
this fixed the issue for me when I encountered it.

1. Create you application Archive
2. Navigate into the Archive and find your Application .app bundle in Terminal
3. Execute the following command: codesign -f -s "3rd Party Mac
Developer Application: My Name" MyApp.app/
4. Upload as normal from Organizer.

Hope this helps.
