I setup all the certificates etc as per the online documentation I found for Xcode since couldn't find any official Xamarin.Mac documentation.
I do use the correct development provisioning profile.
I register the remote connection with:
The FailedToRegisterForRemoteNotifications function keep throwing with an exception.
Error I receive: "Application not properly entitled for push notifications."
The option to enable "Push Notification" is not available in the IDE.
I wrote a HelloMac sample app in Objective C - Xcode and it does get a valid push token where didRegisterForRemoteNotificationsWithDeviceToken execute with a valid token.
I copied the entries that Xcode wrote for "Push Notification" enable to the Entitlements.plist file.
I think there is a configuration issue.
