Mac was a radio repairman and had a shop in Brooklyn, but had trouble making a living. Helen & Mac moved back to Syracuse around 1940, where Mac found work in a factory.

Mac established the Onondaga Television Company in Syracuse in 1940. He was the first Syracusan to register a firm name including the word “television.” In 1948, about two years before the first regularly televised broadcasts in Syracuse, he showed televised broadcasts in his shop at 206 James Street, where he had installed special equipment. On 22 June 1948, he showed the “Charlie McCarthy” show.

Mac’s first TV set had room for 12 channels, but he could pick up only two – one from Schenectady and one from Buffalo. He was one of the few Syracusans to view the 1948 Republican Convention, held in Philadelphia.

Mac was a member of Philo-Mt. Sinai Masonic Lodge. He was a charter member of the Syracuse Television Technicians’ Association. He and Helen owned and operated James TV & Radio Company at 614 North Salina Street until 1980. They were members of Temple Beth El.95
