I have recently purchased a macbook pro 512gb and i have set it up. I had troubles with logging in to app store and iCloud i resolved this by updating to a newer version of el capitan however i cannot sign in to messages or FaceTime. When attempting to sign in to messages a messages flashes up saying that i need to check my network and try again when i know that this is not the case. When i try to login to FaceTime it just continually loads.
MacBook Pro with Retina display, OS X El Capitan (10.11.4)
