hi everyone i am a pc user for 10 years and i am 18 I am going to switch to a Mac, probably Macbook Pro 15 inch on July. Thing is i was watching this macbook pro first boot up video on youtube and on one part it said don't forget to register. What is registering? i mean i am not living in Usa, i will ask a friend of mine to bring one when coming home here, far far away from usa. Would that be a problem to use? i mean not being from usa? i don't want any problems to occur when the nearest tech support is thousands of miles away. thanks for your answers.
