Hi all, I've had these problems for the past little while, at least the past month. In iCloud preferences beside Back to My Mac, it says "iCloud server not responding." I tried turning BTMM off and on with the same result, I've also rebooted. I even went as far as deleting my iCloud account information and signing in again. I even deleted the account files in my user Library and let it reload everything fresh. As well, on Messages I am unable to use iMessage. It just kind of happened one day. I know it's a beta program, but iMessage works fine on my iPhone, and Messages on Mac works fine with other services like Google Talk. Any ideas or tips?
