Billy "Mac" McInerney is Jimmy Mac's brother. He has appeared on several episodes of The Weekly ForceCast and The Clone Wars Roundtable. He is a fan-favorite Roundtable panelist, and on November 22, 2010, he became the first ForceCast personality to have a Facebook page petitioning for his return to the show. (He appeared on a Roundtable episode the next day, although he had been booked prior to the creation of the Facebook page.)
