Mac App Store: circumvent sandbox requirement

Question

As many sources state on the internet, you need to have your app Sandboxed to be able to deploy it in the App Store.

Furthermore, it is impossible to use the access

Answer 1

Irradiated submitted Cinch to the App Store in 2011 before sandboxing was needed and didn't do any substantial updates since then. As soon as they add new functionality or features, they'll need to sandbox the app.

Apple wrote to the developers in February 2012:

Starting June 1 2012, if you have an existing app on the Mac App Store that is not sandboxed, you may still submit bug fix updates without sandboxing your app. In addition, if you have technical issues that prevent you from sandboxing your app by June 1, let us know.

and in May 2012:

If you have an existing app on the Mac App Store that is not sandboxed, you may still submit bug fix updates after June 1.
