Xcode code signed application does not work on 10.8

I wrote a code signed application with Xcode 4.3.3 and it works perfectly with 10.6 and 10.7, but does not open on 10.8 GM. No error message, it just closes itself immediately.

I would start with the assumption that code signing isn't the problem (unless your app does something weird like trying to modify the app bundle). Turn off code signing and see if you still have the problem.

Also, check the system logs, they should contain something about why the app is shutting down.

It works perfectly with code signing turned off.
