Unlink GameKit framework from unity3d mac build

My Mac game is got rejected by saying below reasons.

I’m not using any gamekit or Game centre functionality in my game and also no third-party framework/ plugin.

Kindly let me know how I can unlink gamekit from mac app.


Reasons

2.3: Apps that do not perform as advertised by the developer will be rejected

2.3

The app still links against the GameKit framework but has no apparent Game Center functionality. If we’ve missed functionality within your app that uses Game Center, please use the Resolution Center to describe where we can find this functionality.

If you do not intend to use Game Center functionality, please unlink the GameKit framework, otherwise, if you intend to use Game Center functionality, please add the “com.apple.developer.game-center” entitlement and submit an updated binary.

For information on Game Center, please refer to the Game Center Programming Guide.

If you are using a third-party framework that links against the GameKit framework, you may wish to consult with them for help on unlinking from it.


This was an issue prior to unity 4.5.5.
Update unity and it should not be a problem anymore.
