Racing career
Mack began racing go-karts in 2013, where he instantly had success. During his karting career, Mack won over 50 races across several series including Superkarts USA, Rok Cup USA, and the International Karting Federation.

In 2016, Mack competed at the WSK World Championships driving for Formula One driver Daniel Ricciardo's karting team. It was also during this year that he was signed as a development driver for Phil Giebler Racing.

In 2020, Mack moved to Late Models however was limited to three races due to the effects of the COVID-19 pandemic. He was able to get a full season of Late Model racing the following year, where he would compete at several different tracks picking up multiple wins. Mack also made one start in the SRL Super Late Model division.

In 2022, Mack signed a driver developmental deal with Bill McAnally Racing, which included an opportunity to make his debut in the ARCA Menards Series at Irwindale Speedway. However, due to a scheduling conflict the entry was pulled from the event. A second entry at the Phoenix event was subsequently pulled after Mack got sick needing a overnight hospital stay two days prior to the event.

In 2023, it was revealed on the entry list for the first Irwindale Speedway event that Mack would make his debut in the ARCA Menards Series West, driving the No. 83 Chevrolet for his family-owned team, Mack Motorsports, in collaboration with Bill McAnally Racing, however just days before the race, the entry would be withdrawn. Mack would then make his debut in the main ARCA Menards Series, driving the No. 43 Chevrolet for Tamayo Cosentino Racing at Elko Speedway, where he would finish nineteenth after failing to take the start due to clutch issues. He would then enter in the No. 83 at All American Speedway in the West Series, and would once again withdraw, but would replace Ethan Nascimento in the No. 21 Toyota for Nascimento Motorsports after Nascimento suffered finger injuries that ruled him out of competing in the event, thus paving the way for Mack to make his official debut in the series. He would go on to finish nineteenth after running two laps due to suspension issues. Mack is still scheduled to run two races in the family owned #83 car in the ARCA Menards Series West with a technical alliance from Bill McAnally Racing while also continuing to run Late Models with Kyle Keller Driver Development. Mack was selected to the 2023 NASCAR Drive for Diversity program, but ultimately declined after not coming to an agreement. He instead will stay with Bill McAnally Racing as a development driver for the 2024 season.

Mack is the son of former Indy Pro Series and ARCA Menards Series driver Lloyd Mack, and the nephew of former Indy Racing League driver George Mack. He is also the older brother of NASCAR driver Jayda Mack
