OSX: How to link GameKit framework?

Hi. I currently working on standalone OSX project. It was rejected from app store with this note: "The app still has the Game Center entitlement without linking against the GameKit framework." I read on forum http://forum.unity3d.com/threads/urgent-mac-app-review-team-rejected-because-gamekit-framework-linked.261354/ that with 4.5.4 version Unity stops linking GameKit framework automaticly. I tried to run my project on older version of Unity (4.5.3p4 and 4.5.3p3) but it made my app crash (probably some plugins needs newer version). I also tried to run some application that was recommended on forum to make this linkage (optool) but on current version it's not able to run it for me (errors while building). Is there any other option to make this linkage by Unity?
