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 Desktop Packages, which is subscribed to remmina in Ubuntu. https://bugs.launchpad.net/bugs/1171733 Title: Cannot connect to OS X (Regression) Status in remmina package in Ubuntu: Fix Released Bug description: When trying to connect to OS X hosts I get the following message - Unknown authentication scheme from VNC server: 30, 35 Uninstalling remmina and then installing the version from 12.04 fixes the problem.
