Thanks guys. I was not really asking about apple knocking on my door hehe. I was more worried about system updates and so on.
I'm a very correct guy, I but most of my music from the iTunes Music store, I've never pirated an Apple OS (when I was a windows user 5 years ago, THAT'S another story hehe)
But right now I can't pay for the OS by myself (Need the money for other stuff) so my roomate and I bought it together, 50/50, and will use it like that. No harm done I guess since we PAYED for the thing.... plus I've spend A LOT of money on apple products/itunes music hehe.
thanks anyways guys.
