My macbook is raciest!? what should i do?

I was really excited to get a new mac-book for his birthday. however my new laptop seems to be defective since it seems i have a raciest mac-book. every time ladysman1492 load it up ladysman1492 can clearly make hear the words relax n*gger and eat some fried chicken while i load your applications. My safari browser opens to the ku klux klan every time i load it, my favorites are filled with white supremacy sites even though i never added them? the last straw came today when i tryed to buy a song off itunes and it said "itunes error we dont except drug money for songs" so now im convinced my mac-book is racist what should i do? oh and i bought it on the street so i cant return it... is there like a program i can use to "unraciest" it?
