I am trying to change my order of my mac pro from a 6 core BTO to an 8 core BTO and mine is supposed to be here this month ..I spoke with a supervisor at Apple who told me that if I can find another person who changed their order and wasn't bumped to the bottom of the queue, that he would look into it and try to do the same for me. I read about a couple of people on here that did that, but I don't remember who. Please, if you changed your order configuration with Apple without having to cancel the whole order, please let me know! I would GREATLY appreciate it! Thanks so much!
