Hello, I have an iMac and a Macbook Pro. I would like to use Back To My Mac to share the screens between those two. I have got it working on LAN and when logging into the other computer as the computer's user. Now I would like to be able to login to my Macs over the internet. I have read that to do this I should use Apple IDs. When I try to share the screen on one of the Macs, I get the opportunity to login with an Apple ID I have set in "Users and Groups" but when doing so I get an error message. Sometimes the error message will be: Other times it will be: (Sorry, those error messages are roughly translated from Danish) Does anyone have an idea how I can get authentication using Apple IDs working and how I can use Back To My Mac outside LAN?
