As you can see, OS X runs fairly smoothly, and can handle iTunes, video games, and other duties without complaining. I should point out that there is no legal way to install OS X on an MSI Wind or Medion Akoya mini. Apple has a pretty restrictive license for OS X, and even if you’ve purchased a legal copy of the operating system, you are prohibited from installing it on non-Apple hardware.
But if you want to find some directions, check out the MSI-Wind.de forums. Apparently everything works except for the webcam.
