I am experimenting with an Amazon EC2 server running Windows Server 2008 R2 Datacenter. I would like to have the machine run a theme (preferably Aero) other than Classic. Is there an alternative app to mRDC that would let me show a theme over RDC?
I know only of one alternative to mRDC which is Cord. But I'm not sure whether Cord supports themes.
I use iTap mobile RDP which supports composition (you may have to enable it in the connection's settings).
It's not free, but does come with a trial.
As far as Mac RDP clients go, this one's the best I used. It's been stable for me, but since I bought it from the Mac App Store one update has gone out to fix bugs that some users were experiencing.
I would recommend it after using the trial, to make sure it works well for you.
