Finally. All you Mac users can IRM protect your Office content with Office 2011 for Mac.
If you want to start playing with this functionality you need to install SP1 RC (I suggest installing it in a test environment), on your WS2008 R2 RMS server. This will give you a sweet file in your certification directory called maccertification.asmx.
To set it up, you need to follow these instructions.
There you go. Now we all get to wear our ‘big boy’ pants and play in the sandbox together. 🙂
