Linux (linux mint 14 mate) i have gotten wine to work with neverwinter however a native client would be nice even though the wine setup for neverwinter was relatively easy
I have gotten it to work on Wine 1.5.30 on linux im unsure if the linux way will work on mac but if everything is the same once you have the version of wine that i previously stated then type "winetricks dotnet40 ie8" then install neverwind it may give a error during install ignore it the game works 99% all except the zen…
I have everything works(except the zen store) you need a 32bit install (or 32bit preface on wine) the 1.5 version of wine (i use the beta one) then run from terminal "winetricks dotnet40 ie8" without the quotes of course after that install the game and it should work fine
