We've identified the most pressing need for easyDNS members to be a native mac client, as other platforms seem to have plenty of third-party clients.
This dynamic DNS client for Mac OSX runs as a daemon process and checks both your local computer address and LAN address if applicable.
Simply download, unpack and drag into your "Applications" folder, then run and enter your information.
You can report any problems or comments either here, or open a ticket directly with support.
