Mac’s Real Name In It’s Always Sunny In Philadelphia Still Makes No Sense

When It’s Always Sunny in Philadelphia finally revealed Mac’s full name, it didn’t line up with the clues that the show had given in previous seasons. For the first six seasons of It’s Always Sunny in Philadelphia, Mac’s full name was never mentioned. His name was finally revealed in season 7, episode 12, “The High School Reunion.” Upon arrival at his high school reunion, Mac is given a nametag bearing his real name: Ronald McDonald. The fact that this is the same name as the clown mascot of McDonald’s explained why Mac had avoided using his full name for so long.
