I disabled Apple Push Notification Service but it's still attempting to connect to Apple servers
Found this googling around:  


  If you don't use FaceTime, put this in a Terminal window to get rid of apsd permanently: "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.apsd.plist"


This will unload apsd from launchctl (the process that launches it at startup), but you'll still need to kill now.
