MacGyver's first name was originally intended to be Stacey, as seen in a press release from Paramount. However, it was never confirmed in any episode, and remained a mystery until the seventh season; whenever he is asked about it, he says he dislikes his first name and quickly changes the subject. His grandfather, Harry Jackson, calls him "Bud" or "Buddy". Most of his friends and colleagues call him by his last name MacGyver or simply "Mac". In the final season, his first name is canonically revealed to be Angus when, while knocked unconscious and hallucinating, he meets a 7th-century man named Ian M'Iver ("son of Ingmarr") whose son has the same first name. This revelation is repeated in the series finale, which introduces MacGyver's son as having the middle name Angus, as well as on the packaging of the MacGyver DVD season sets.
