Hired by San Jose State in 2010, MacIntyre became a head coach for the first time in his career. As San Jose State head coach from 2010 to 2012, MacIntyre coached a program that improved from a one-win season in 2010 to a 102 record in 2012.

After the 2012 regular season but before the 2012 Military Bowl, MacIntyre resigned from San Jose State to accept the head coach position at Colorado.
On December 10, 2012, the University of Colorado announced that it was hiring MacIntyre to replace coach Jon Embree, who was fired after two seasons. On September 2, 2013, MacIntyre won his opening game over Jim McElwain and rival Colorado State on a neutral field at Sports Authority Field at Mile High in Denver. His positivity and decision-making during the game were praised. Coming off a 111 season in 2012, Colorado posted a 48 record in 2013. On February 20, 2014, the University of Colorado Board of Regents extended MacIntyre's contract through the 2018 season. Colorado then went 210 in 2014 and 49 in 2015.
Everything came together for Colorado in 2016. On October 22, Colorado became bowl eligible for the first time since 2007 after beating Stanford 105. Two weeks later, they clinched their first winning season since 2005 with a 2010 victory over UCLA. On November 26, 2016, MacIntyre led the Buffaloes to a 27-22 victory over Utah, clinching the first Pac-12 South Division Championship in school history. MacIntyre was named the Pac-12 Coach of the Year for 2016 after the Buffaloes were picked to finish last in the division prior to the season. He was also awarded the Walter Camp Coach of the Year Award becoming the second Colorado coach to earn the award, on a team led by his first recruiting class, assembled just weeks after his hire.
On January 10, 2017, MacIntyre signed a 5-year, $16.25 million contract with Colorado that will see him under contract with the Buffaloes through the 2021 season.
