Early life
Harry McKenzie was born on February 17, 1990, in Portland, Oregon. He already had a background in music, as he began playing the violin at seven and started playing the drums in fourth or fifth grade. His older sister introduced him to hip hop via the radio Jammin' 95.5. Mack began rapping in sixth grade, at 12, with his friend Brady B, an aspiring DJ. They formed a group called State of Mind and released an album when they were in middle school. Mack went by the alias MC Wundur at this time.

The group continued making music into high school and added two more members: Elan, an MC known as Mighty Misc, and Jack Baars, a DJ and producer known as DJ Malfunktion. They began to take it more seriously starting in their sophomore year and booked venues to perform at and sold CDs. Originally from Portland, Mack moved to California in 2008 to major in Jazz Studies at the USC Thornton School of Music at the University of Southern California, as at the time he wanted to become a jazz drummer. He enjoyed the improvisational aspect of jazz and began to practice freestyling to work on his ability to do so. His roommates would test him on his freestyling every night. He graduated in 2012.

Career
In 2016, one of Mack's friends, Jacob Mann, a jazz pianist and composer, needed some promotion for his recently released album, so Mann asked Mack to freestyle on a remixed jazz beat he had made. Mann recorded Mack freestyling in a car, remarking at the changing scenery, and uploaded it to YouTube, which later went viral, making it his first breakthrough. Meanwhile, Mack's college roommates eventually made him start practicing in public, in places such as Venice Beach. He uploaded a video of one of his sessions in February 2017 titled "Venice Beach Freestyle (Part 1)", which reached nearly a million views within a few months, sprouting him into the mainstream. He had only just started uploading videos and realized he had an audience for it. In March, Mack freestyled on the Power 106 radio for fellow rapper Joey Bada$, who threw words out for Mack to implement into the freestyle, a common occurrence in Mack's work. This event was covered by XXL, which praised Mack for his lyrical abilities. Mack came back onto Power 106 to freestyle for Kendrick Lamar in June, Casey Veggies in July, and Macklemore in September. Also in September, he freestyled on The Ellen DeGeneres Show and also made a short film with Red Bull, touring them around Los Angeles.

In June 2018, Mack partnered with Mitsubishi Motors to create Harry Mack Freestyle Test Drives, a marketing campaign where Mack freestyle about the features of the car a person was driving as they tested it out. United Talent Agency represented him and helped him make the deal. Mack independently released his first album, Contents Under Pressure, on January 18, 2019. He eventually signed to Mush Man LLC in August 2019. In December 2020, he interviewed Counter Strike: Global Offensive player n0thing and freestyled over his gameplay on Twitch. He also teamed up with Marc Rebillet in May 2021. In celebration of him reaching a million subscribers on YouTube, Mack freestyled for ten hours straight in June 2021. In August, he participated in PogChamps 4. Mack performed at the Shacknews E6 in 2022. In this year, he also embarked on a tour to the United Kingdom. For his 2023 U.S. tour, Odyssey, he was sponsored by Starbucks. He had previously collaborated with the coffeehouse chain to host Reverse Roasts, where Mack performs freestyles to uplift people. To promote the tour, he appeared on TNT and freestyled for the hosts of the show. Mack helped promote the film Teenage Mutant Ninja Turtles: Mutant Mayhem in 2023 by performing a themed freestyle for Seth Rogen and Ice Cube. He did the same in 2024, this time promoting Bad Boys: Ride or Die with Will Smith and Martin Lawrence. He had previously performed at the The Streamer Awards 2024.
