 MacGyvers given name was not revealed until near the end of the  show in the episode "Good Knight MacGyver: Part 2". Before that when  someone asked, "Do you have a name?" he answered, "Yes," but did not  reveal it. MacGyvers name was originally Stace MacGyver (according  to the script for the pilot). Nobody used the name during the pilot;  when it slipped out and became general knowledge to the fans, they  decided to just call him "Mac" or Macgyver" for the duration. The  name Angus was chosen because they felt it was unusual and something  with an "ick" factor (although, not according to any Scots in the  audience). The name was "suggested" from a poster for a charity  event in Canada, where the series was being filmed at that time.
