CoRD is a Mac OS X remote desktop client for Windows servers running Microsoft Remote Desktop or Terminal Services.
@tpierce777 CoRD works an Mavericks ! I use it since Mavericks release without problems
Love the program, but come on, I want to upgrade to Mavericks (OSX 10.9), and you don't support it. It has been over a year since anyone has updated it! I'm not a programmer, but it can't be that difficult to make it work. Please!!!
