Microsoft RDP Client 2.0 for Mac

So frustrating! I installed the RDP Client to access my virtual machine at work - but, guess what, out of some weird reason MS decided not to support TS Gateway Services. 

This is really strange as this functionality has been available for quite a while and there are good 3rd. party clients for the iPad , iPhone and Android (I recommend iTap RDP - the best iPad TS Gateway Client out there).

Well - I guess this means no work for me on my new iMac. Does anyone know about a RDP Client for MAC that does support TS Gateway Services ?
