Advice on app - store process -- 2

Job ID: 31992026

Budget: $250 – $750 USD

We need some assistance in packaging our app for the Mac store. Basically, how to assign our developers certificate, create a distribution package, load icons, and/or testflight, etc.

This is for a Mac OS app, not mobile, ipad/iphone.
Desktop only.

We JUST need to understand how to prepare the app for the App store.

This does not need to be re-coded, or programmed into another language, just advice on the process of app certification for sending to testers.
