Game Center for Mountain Lion not working

For those having problems with Game Center on Mountain Lion, showing an empty green box, try Repair Disk Permissions. Worked for me.

Having the same problem but repairing the disk permissions didn't do anything :/ Hope it'll get fixed soon. Seems like it's not affecting many people though

Having the same problem . Disk repair did find a couple of issues , but Game Center still does not work. I never had an IPhone nor used game center before.

My game center not accept ACCOUNT info like mail and psw ... i'm sure i've typed rught datas ! ... ****

I have this same issue, black screen

same here. blank green screen.

I"m having the exact same issue. Repair disk permissions didn't do it for me either.

Same here. Repairing disk permissions didn't help the problem.

I was having a similar issue. The disk permissions didn't work for me however I found another method. First quit Game Center, then go to launchpad or the Applications folder and open Chess. Once its opened Game Center should automatically relaunch and the empty green box gets loaded with the Terms and Agreements and once you accept those it will take you through the process of setting up the profile.

Hope this helps.

Didn't work for me :/ Terms and conditions weren't loaded in the green box even though I accessed it via Chess

Same. It didn't work for me either. I closed game center, loaded chess and the game center app loaded, but still no terms and conditions--just an empty green box.

This worked for me 🙂 Thank you!

Have you used Game Center on other Apple devices like an ipod touch or iphone?

None of these solutions work for me either?? 😟

Okay got it, signed onto my sisters iphone gamecenter and accepted terms and conditions there.. 🙂
