Is it because they are marked as 'Not Live'? Is it not working because I'm trying to test in the Unity editor? I tried launching the game from the icon which was created during the Build process, and I get the same results. I also get an error about not being able to find the achievement I created in iTunesConnect. I send myself a debug message which looks like Authentication completes successfully, but I'm not signed into Game Center on this Mac.

The game plays successfully in the Unity editor, but I was expecting to see a Game Center log-in dialogue box. I have not submitted the game submission for review because I need to test the code first.

In 'App Store' tab -> 'Prepare for Submission' I've ticked the 'Game Center' toggle and included all the achievements and leaderboard I made on the other screen. They all say 'Not Live' in the Status column. In 'Features' tab -> 'Game Center', I've created the (46) Achievements and (1) Leaderboard. In iTunesConnect - I've created the game record on the iTunesConnect website. I've built the game on a Mac as a Standalone Mac OS X. In Unity - I've included code from website to test Logging in to Game Center and achievements. What is the workflow to test Achievements and Leaderboards before submitting the game to the app store? I want to include Achievements and Leaderboards. I'm attempting to port my game to the Mac App Store.
