An operating system. Nice controls, and in my opinion, better, faster, and easier than Microsoft Windows.
Just a short few years ago, it was a privelege to own a Macintosh computer, but they have now been ruined by fanboys and fangirls, much like iPods.
Porter: What kind of computer did you say you use?
Ivan: Macs
Porter: Yeah me too! They're great!
Ivan: You are stupid. You're a total Windows person. You've been using a Mac computer for almost 1 year, and you think you're special?
Porter: Uh...
Ivan: I have used Macintosh all my life, since about Mac OS 5. Do you even know what Mac OS 9 was?

A great rapper from New Orleans best known for his albums Shell Shocked & World War III . Started out Lil Mac and came out with his first album in 1989. He was signed to No Limit Records until 2001 when he was wrongfully accused of a shooting he clearly didn't commit. Was at a bar performing when a man on the other side of the room shot and killed somebody. A ballistics test showed he didn't even fire his gun, plus the REAL killer confessed. Unable to find any actual evidence of his guilt and envying a successful black man, racist white supremacist prosecutors used one of Mac's lyrics as evidence against him. Despite appeals, the bigots convicted Mac of manslaughter, when that wasn't even the right crime, and locked him away from his wife and son because the Louisiana jury hates seeing a black man making money. Humble man, never arrested ONCE before, but somehow guilty of a shooting when he never fired his gun. Appearently the days of Jim crow are NOT far behind us. Now 10 years later, McKinley Phipps still sits in a prison cell, his son forced to be his own father figure. Very sad.
Corey: hey u heard of that rapper Mac from no limit? He got a bangin ass song called slow ya roll.

Joe: yea, the dirty prejudice jury locked him up and framed him so he can't make dope albums any more.
