I just got a Macbook Pro today. I made my first account, and then everything was working perfectly. I was getting my messages on my Macbook, etc. Then I deleted that account and made a new one, and suddenly none of that works. I'm really at a loss here. Edit: I called Apple and the guy I was talking to had no idea what the issue was either. However, he told me to make a new user account and try it on there. Sure enough, it worked. So I just deleted the user account that gave me problems and started on this new working user account. No big deal since I didn't have much on there yet. He then tried to find out what exactly the issue was, and he just couldn't, so I said it was fine and that I didn't mind not knowing just as long as I can use continuity and handoff now. So if anyone else is having problems using continuity or handoff and nothing else seems to solve the issue, try it on a new user account.
