Transferring OS X license what does it exactly mean? I'm about to restore macbook to factory settings (but not to sell it) and of course I used google and found this: http://support.apple.com/kb/PH11273?viewlocale=en_US&locale=en_US Easy and simple. But then I found this post: https://discussions.apple.com/thread/4390401?start=0&tstart=0 and in the end we can read: If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License. Do I need to bother with transferring license when I will not sell my macbook?
