WampServer

I used WAMPP for years with Windows. Now I switched to iMAC and here I use MAPP. The webroot is located on its own partition. Because of the need to test websites also under IE, I have installed ParallelsDesktop+Windows. But from there I have no access to the "localweb". So I tried to install WAMPP and re-define the document root. The localweb is inaccessible anyway.
Have you any recommendation?
