Are you really sure bout that. I`d heard of MBPs not whining under winblows but heat is worse with WinBlows on your MB/MBP than OSX. I m just guessing but it`s atleast 10-15 degrees hotter when I m running WinDozzzze than OSX on my MB.
LOL. What do you actually mean by saying OSX runs harder. Sorry i didnt get what you are trying to imply. I am not even sure it`s a positive for OSX or a negative .
