This is probably not worth your time to read. Quite often I see people posting about their MAC but meaning to talk about their Mac. Your computer isn't a MAC! It's called a Mac, dang-diddly-ang-it! I nominate myself to fix this! Therefore I must explain what a MAC is (in reference to computers and computer-related equipment), as opposed to a Mac. If for no reason other then to make myself feel better.. MAC = An acronym for Media Access Control, the unique identifier of your network card, also known as an ethernet hardware address. Mac = The shortened name for Macintosh. A computer built by a California fruit company that has a small, but virulent, following of groupies. Please, don't offend your Mac(intosh) by referring to it as an ethernet hardware address.
