What is the best iMessage account to attach to another machine?
What is the best iMessage account to use so that I can attach to someone else machine in order to help them? I have Google, Aim, Bonjour and me.com and they are enabled. I am getting the camera in the "Buddies" dialogue box and I put the accounts in another person's machine but we can't connect.
iMac, OS X El Capitan (10.11.2)
