Game centers
I have an iOS game with one Game Center. I published the game a few months ago and now I am working on the OSX version. I want to use the same leaderboard for both versions of the game, which means I need to create a Game Center group. The problem is that Apple forces you to change your leaderboard ID when you move them to a group:
Group IDs must start with grp.
Now if I do this, I will need to update the iOS version of the game so that my users can post their ratings, and if I release an update to the iOS version of the game, players who do not install the update will no longer be able to use the leaderboard.
My question is, is there a way to use the same leaderboard in both versions of the game without updating the iOS version?
Thank.

You don't need to update the iOS version. As you might have guessed, the old IDs continue to work (under normal circumstances). If you add new leaderboards or achievements, they will be added to grp. * Although (requires an update if you want them to be picked up by the iOS version).
Sandbox grp. Leadboard does not inherit real-time scores from the iOS version, old leader scores for the iOS version of iOS should still be intact.
Live breasts. leaderboard must inherit current scores from non-iOS group leaderboards.
In general, isolated leaderboards and achievements can fade from time to time, and it sometimes takes several times (sometimes several hours) to change the iTunes connection configuration to reflect correctly in the GC database for your application.
