Hi,
Here is the windows server forum involved with RDS/VDI deployment. Remote Desktop Connection Client 2.1 on mac os platfrom:http://www.microsoft.com/mac/remote-desktop-client
If it doesn't work,I suppose this issue should be asked in either Azure instance forum or Mac OS X forum for this issue.
Regards,
Clarence
