Is it safe to use the charger that came with this MacBook:
With this (new) MacBook?
My cousin is trying to convince me that if I use my old MacBook's charger with my new MacBook, that it's going to mess up my new MacBook because "the new MacBooks are made more green, and energy efficient, and now the charger that came with your new MacBook doesn't give off as much electricity and the old charger is going to mess it up."
Is my cousin stupid and full of sh*t, or does he actually know what he's talking about?
