I apologize if this has been asked before, or I posted this in the wrong section.
Well, I've just ordered the 13" Macbook Pro from the Korean Apple Store (I'm living in Korea). My question is how does the whole free upgrading thing work? I asked this because I bought that Mac with the help of a friend who used his iTunes account to order it. I'm afraid that I won't be able to redeem the code for mountain lion for my own account.
Also, I am new to the whole Mac OS thing. Does Mac OS X allows you to freely switch between English and Korea? (Windows does not as far as I'm concern
)
Oh and I would be really grateful if you could link me to a site or any place that teach the basic or tips and tricks for a new mac user like me
. Thank you guys in advance
