Rob McElhenney Is Now Rob Mac: Why The “Sunny” Star Changed His Name
Rob McElhenney, the beloved star and co-creator of It’s Always Sunny in Philadelphia, has officially changed his name—sort of. The actor, best known for playing the eccentric and fitness-obsessed Mac, now prefers to go by “Rob Mac” in his professional life. But why the sudden shift?
Fans were surprised when McElhenney—or should we say Mac—updated his Instagram and X (formerly Twitter) handles to @robmac, signaling a more permanent rebrand. While the change might seem minor, there’s a deeper meaning behind it.
Why Did Rob McElhenney Change His Name to Rob Mac?
1. A Nod to His Most Iconic Role
McElhenney has played Ronald “Mac” McDonald since It’s Always Sunny in Philadelphia premiered in 2005. The character has evolved from a clueless, self-centered bar owner to a surprisingly deep, emotionally complex figure—especially after his famous “Mac Finds His Pride” dance scene in Season 13.
By adopting “Mac” as part of his professional name, Rob is paying homage to the role that made him a household name. In a 2023 interview with Variety, he said:
“Mac is a part of me. I’ve spent more time as him than as myself at this point. It felt right to embrace it.”
2. Simplifying His Brand
McElhenney’s full last name—McElhenney—isn’t the easiest to spell or remember. Shortening it to “Mac” makes it more marketable, especially as he expands his career beyond Sunny.
This isn’t the first time a celebrity has simplified their name for branding purposes:
-
Chrissy Teigen dropped her last name (“Teigen” instead of “Teigen-Hough”)
-
Kanye West rebranded as “Ye”
-
Elon Musk’s son was briefly named “X Æ A-12” before changing it
3. A Fresh Start After Wrexham Success
With the massive success of FX’s Welcome to Wrexham—the docuseries about McElhenney and Ryan Reynolds buying Welsh football club Wrexham AFC—Rob is stepping into a new era.
A source close to the actor told Deadline:
“Rob sees this as a new chapter. Between Sunny, Wrexham, and his production work, ‘Rob Mac’ represents where he is now—more confident, more established.”
Fan Reactions to the Name Change
Social media had mixed responses:
-
Twitter User @SunnySuperfan: “Rob Mac just hits different. It’s like he’s fully embraced the chaos.”
-
Reddit Thread on r/IASIP: “First he gets shredded for Mac, now this? Legend.”
-
Instagram Comment: “Does this mean Mac is finally getting a spin-off?!”
Even Ryan Reynolds jokingly tweeted:
“Rob McElhenney was already hard enough to spell. Now it’s just Rob Mac? Fine. But I’m still calling him ‘McPoyle’.”
What’s Next for Rob Mac?
Beyond It’s Always Sunny (which was renewed for Seasons 17 & 18), McElhenney is working on:
-
More seasons of Welcome to Wrexham
-
A rumored Mac-centric Sunny spin-off
-
Expanding his production company
