Can I change my MAC address to be the same as my old MacBook so it will stop rejecting my iPod? I was wondering if I could change my MAC address to be the same as my old MacBook so it will stop rejecting my iPod or trying to force me to erase it? Or is it better to just generate an entirely new one? Thanks!
Making the name identical will not change acceptance.
You have to deauthorize the ipod from the old MB and then authorize on the new MB  .
