Hi, this has probably been asked before, and I apologise if it has,but does anyone know if it is indeed possible to get either ML or Mavericks working with an imac with onboard ATI x1600. I believe im having difficulty because the lack of a 64-bit driver.Has one been written yet? I managed to get the OS to install (imac core2duo, 5,1) using SFOTT, but cant for the life of me find a suitable kext anywhere.
