History Characters / ItsAlwaysSunnyInPhiladelphiaMac

* SuicideIsShameful: He’s the only one who thinks they should do something about the suicidal jumper. Not out of any moral decency, just because suicide is a mortal sin.

** By season 15 and definitely 16, he actually seems over Dennis. Not to the point of standing up to him, but when Dennis reveals he’s Johnny (because it’ll get Mac out of the house), Mac is convinced Johnny is real. Early Mac would have been convinced that Dennis actually loved him.

* CharacterDevelopment: Actually manages to accept his homosexuality for good in "Hero Or Hate Crime?". While coming to terms with being gay doesn't do anything to affect [[DirtyCoward his]] [[{{Jerkass}} horrible]] [[ManChild personality]], his insecurities about who he is are a defining part of his character, and so overcoming them, even if it's only slightly, is still a big step for him.

* IJustWantToBeLoved: Along with his desire to be an ultra-badass, Mac is also deeply insecure about the possibility that his friends and parents don't care about him, and will pathetically do whatever he can to earn their affection. However, his actions tend to only lead to them disliking him even more.

* HereditaryHomosexuality: Mac, whose ArmoredClosetGay status is a longstanding RunningGag for most of the series, has two gay cousins. The first one appears as an easily forgotten BitCharacter from the pilot. The other one, "Country Mac", is presented as a {{Foil}} who acts like Mac but without all his bad qualities (including being open and confident with his sexuality). Mac's father has also displayed bisexual tendencies, although that [[SituationalSexuality might be a result of having spent years in prison]]. Season 16 gives him a gay uncle too.

* EatTheDog: Literally. After spending month [[SanitySlippage going insane]] from living in the suburbs and feeling like Dennis is neglecting his feelings, Mac spitefully allows their dog Dennis Jr. to starve to death and secretly feeds it to Dennis. When Mac reveals the truth, Dennis is appalled while Mac belts out an EvilLaugh far more terrifying than anything we've seen from him before.

* HeavenSeeker: Much to the incredulity of his friends, Mac will occasionally refuse to participate in the Gang's schemes if he believes they compromise the likelihood of him getting into heaven (which, for him, is populated by hunky angels and a buff shirtless god). Played for ''extreme'' drama in "Mac Finds His Pride," when [[spoiler:Mac tries to communicate to his father the tension he feels between being gay and wanting to be accepted by God through a beautiful and genuinely moving contemporary dance routine, with a woman representing God as his partner.]]

** While he's always presented as far, ''far'' less skilled of a fighter than he claims to be, the show switches between whether he is [[UnskilledButStrong physically pretty strong but lacking in any stamina or fighting ability]], or completely weak in every sense of the word. He can also range anywhere from showing explicit interest in women ([[NoAccountingForTaste and having no standards]]) to being in a TransparentCloset depending on what's funniest (this was dropped later on and he has officially been out of the closet since Season 12).

* InsaneTrollLogic: He believes that due to his realization that he's gay, God can't possibly be real. After surviving the boat sinking, he flips it around, claiming to be straight because God supposedly saved them from drowning.

* AnythingThatMoves: Had sex with Margaret [=McPoyle=], a woman he's openly disgusted by, simply because she offered. In general, during the early seasons, if Mac has the option of having sex with something, he'll have sex with it. This is probably due to him being a closeted gay man; he was so adamant about proving his non-existent heterosexuality that he was willing to have sex with any woman who would accept him, regardless. He also isn't at all repulsed when Frank tells him that a monkey may have "fucked [his] mouth."

* HasAType: While he's not picky about who he has sex with (see AnythingThatMoves), he has consistently shown a preference for beefy hunks (making his attraction to unfit and waifish Dennis very ironic).

** While probably the [[TheFriendsWhoNeverHang least close pairing in the group]], they do seem to get along fine when [[ToxicFriendInfluence the rest of the Gang]] isn't around, like in "The ANTI-Social Network" or "The Gang Hits the Slopes".

* {{Schemer}}: When he was younger, he was a drug dealer in high school and ratted on all the other dealers to free up the market and he also created The M.A.C. system for seducing Dennis' castoffs: Move-in After Completion.

* IfItsYouItsOkay: Even early in the series, it's easy to interpret his sexual encounters with women as [[AmouredClosetGay him trying to act straight]] or as more of a status symbol than actually enjoying the act itself. But he genuinely enjoyed sex with Barbara and actually has lingering feelings for Carmen after their breakup.
