Boyett died Wednesday of complications from pneumonia and kidney failure at Holy Cross Hospital in Mission Hills, Calif.
Boyett's early television credits in the 1950s included "Playhouse 90," "Four Star Playhouse," "Perry Mason" and "Sea Hunt." Boyett also guest starred frequently on "Highway Patrol," "Family Affair," "My Three Sons," "Emergency!" and "Knot's Landing." However, Boyett was best known for playing Sgt. "Mac" MacDonald on the TV series "Adam-12."
Boyett is survived by his wife of 48 years, Joan; son, Keven; daughter, Suzy; two granddaughters; and his brothers, John Olafson and Wallis Collins.
A private memorial service will be held next week. The family suggests fans make donations in Boyett's name to the Motion Picture and Television Fund or the Music Center Education Division.
