Development
On May 9, 2019, CBS renewed MacGyver for a fourth season, with Terry Matalas replacing Craig O'Neill as co-showrunner alongside Peter M. Lenkov. It was later revealed that the season would premiere on February 7, 2020, after being pushed to mid-season to make room for Magnum P.I. on CBS' Friday schedule. On November 6, 2019, it was revealed that CBS had ordered nine additional episodes which would’ve brought the season order to twenty-two episodes. However, on March 14, 2020, it was announced that production on the fourth season had been shut down due to the COVID-19 pandemic. As a result, CBS later decided to save some of the remaining episodes for season 5 and end season 4 after episode thirteen.

Casting
On May 9, 2019, it was announced that Levy Tran, who plays Desi Nguyen, was expected to be promoted to series regular for the season, after recurring during the previous season. On June 7, 2019, it was officially confirmed that Tran would be promoted to series regular. On June 28, 2019, it was announced that Henry Ian Cusick had been cast as a series regular in the role of Russ. On February 18, 2020, it was announced that Jorge Garcia would guest-star in an episode as Jerry Ortega, his character from Hawaii Five-0, however, his appearance was later delayed until season 5. On February 20, 2020, it was revealed that Jeri Ryan has been cast in a recurring role as MacGyver's aunt Gwen. All four members of the comedy troupe The Tenderloins (James Murray, Sal Vulcano, Joe Gatto, and Brian Quinn) guest-starred in episode seven as restaurant employees. Tate Donovan and Peter Weller both reprised their roles from previous seasons as James MacGyver and Elliot Mason, respectively.

Lenkov's termination
Following the conclusion of the season, Lenkov was fired from both MacGyver and Magnum P.I., on July 7, 2020, following allegations that he created a toxic work environment. Lenkov had also been the showrunner of Hawaii Five-0, which concluded in April 2020, three months before his firing. He was replaced by Monica Macer for season five. In response the Lenkov's firing, series star Lucas Till said that Lenkov's actions caused him to feel suicidal and that Lenkov bullied, verbally abused, and body-shamed him, which a spokesperson for Lenkov claimed was not true.
