Who is the Intel retiree that joined Apple and contributed to making it a successful business?

The correct choice identifies Mike Marcola, an Intel retiree who significantly contributed to Apple’s success during its early years after joining the company. Marcola brought valuable experience and expertise in the semiconductor industry, which enabled him to influence Apple's product development and technological advancements. His ability to integrate high-performance processing capabilities into Apple's computers helped enhance product offerings, ultimately leading to the company's growth and establishment in the tech market.

In the context of the other individuals listed, while Steve Jobs and Steve Wozniak are co-founders of Apple and had enormous impacts on the company's trajectory, they were not Intel retirees. Ron Wayne, another co-founder, had a brief involvement with Apple and is less known for long-term contributions compared to Marcola. Thus, Marcola stands out as the individual with a background at Intel whose skills directly contributed to the evolution of Apple into a major player in the technology industry.
