I am getting the following message when I try to connect to iMessage on my Macbook Pro: Could not sign in. Please check your network connection and try again.
Hello,
I am not sure what is going on but I am unable to sign into my iMessage. I am trying to sign in but I keep getting the message: "Could not sign in. Please check your network connection and try again." I can log into iTunes and all other things that request my Apple ID except the iMessage. I hope someone can help me out.
MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.2)
