For other's like me on 14.04 looking for a fix to this issue: This ppa: https://launchpad.net/~remmina-ppa-team/+archive/ubuntu/remmina-next has an updated version of the package available which resolves this issue.
One other thing that might worth mentioning from https://help.ubuntu.com/community/AppleRemoteDesktop is that the color- depth must be set to 15 bit to work with OSX servers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1171733 Title: Cannot connect to OS X (Regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/remmina/+bug/1171733/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
