He appointed to the Board of Commissioner at the Port Authority of New York and New Jersey by New York Governor George Pataki, until he was forced to resign in 2009.

He has been an honorary deputy superintendent of the New York State Police since 1995 despite having no law enforcement experience. He frequently appeared at State Police formal functions in full dress uniform, which reportedly angered State Police rank-and-file troopers.

Mack has a longstanding relationship with the Nassau County Police Department where he has served as an unsalaried assistant commissioner since at least the mid-1980s. The department issued Mack a police badge.

Metropolitan Transportation Authority
Mack was a Vice Chairman of the Metropolitan Transportation Authority from December, 1993 until September, 2009. He is the Chair of the Long Island Rail Road/Long Island Bus, Bridges and Tunnels Committee, and a member of the Capital Program Oversight, Finance, Interagency Coordination, Audit, Governance, Diversity, Safety and Security, Capital Construction/Planning and Real Estate, New York City Transit, Metro-North Committees. According to Mack, he used the Long Island Rail Road between five to ten times a year. His term ran through June 30, 2009.

In May 2008, New York State Attorney General Andrew Cuomo announced that the MTA policy of giving free lifetime passes to current and former board members violated New York State law. The MTA board initially resisted changing this policy.

Mack was reappointed to the MTA board in 2019 as the representative for Nassau County. In 2022, the MTA took away placards from MTA board members which had allowed them to park anywhere in the city legally. This led Mack to throw a tantrum. After losing his placard, Mack began voting against MTA plans for congestion pricing in New York City, which had been in the works since 2019.

Mack has donated to scholarships and capital programs at his alma-mater, Hofstra University. The David S. Mack Sports and Exhibition Complex, the Sondra and David S. Mack Student Center and Mack Hall are named in his honor.
