Mac is kind, intelligent, polite, responsible, imaginative, and caring. He is generally calm, sensible, and mature for his age. He is very patient with his friends, especially Bloo, even when Bloo causes trouble. He can sometimes be shy, nervous, or frustrated, but he always tries to do the right thing. He is loyal, thoughtful, and deeply attached to his imaginary friends.
Speaks in short, workmanlike bursts with a dry, warm humor; tends to look past you at whatever needs fixing.
