RDP on Mac

I am a new user to F5's BigIP. I have created a webtop where users can access the MS RDP by clicking on the button. All windows users can access this but when a mac user logins to the page he does not see this button for RDP. I am trying to find out if it is possible to have Mac users access the RDP using the webtop or any other way. I know the Mac users will have to download the windows RDP client on their machines but how can I invoke it to launch automatically when they click on the RDP link. Please let me know.

 

 

 

Thanks in advance to all the gurus.
