Unable to register for Apple Push Notification Service on Mac

Question

I downloaded the PushyMac sample application from Apple website but cannot figure out why I couldn't register for push notification upon application startup. Here's the error I get

2013-02-27 19:53:49.737 PushyMac[61525:303] applicationDidFinishLaunching:
2013-02-27 19:53:49.738 PushyMac[61525:303] didFinishLaunchingWithOptions:

Any idea why this might happen?

Answer 1

This happens when your app is not code signed properly

Answer 2

I just received the same error message after signing out and signing back in to iCloud on my Mac. I resolved it by going to the Capabilities tab of my target in Xcode. Under iCloud, a problem was shown, which was automatically fixed by pressing the fix button.
