Apple usually has an "Up to date" program that allows buyers of any Mac product that is purchased within a specified time span before the official launch of Mavericks, or purchase a Mac that does not ship with Mavericks AFTER the official launch, to update for free.
Everyone else will have to purchase it.
I know that OS X Mavericks has not yet been released for public use. However, I would like to know that is it possible to update current generations of MacBook Airs featured with Intel's fourth generation of processors, Haswell, to Mavericks for FREE after it releases for public use?
Thanks in advance!!!!
