Just a maintenance update. I've put up "code signed" versions of the OS X versions of Mirror Mirror, Yorick, and Gordo on the web site. This is to address the issue of the dialog box that appears when you launch the puppet and OS X warns you that it is from an untrusted developer. (I guess that means I'm now a trusted developer!)
The versions are exactly the same as the previous versions otherwise. If you already have them working in your environment, there is no need to update unless you want to suppress that dialog box from appearing.
