Steve Wozniak claims Steve Jobs' personality changed after Apple's success.
The company's co-founder - who started the firm alongside Jobs back in 1976 - suggested once the company took off, the late tech pioneer didn't have the same sense of humour as he did in the early days.
Speaking to Guy Kawasaki on the 'Remarkable People' podcast, he said: "He got kind of strict."
Wozniak insisted while he never really cared about making money, Jobs - who sadly passed away aged 56 in 2011 - wanted to become an "important person in life".
He explained: "Steve wanted to be important, and he had zero money. So he was always looking for little ways to make a next step in money, [and] he wanted to be that important person in life.
"And this was his big chance, because now he was founder of a company with big money being put in."
He added: "Because he talked about those people all the time, he wanted to be one of them, and he felt he had it.
"He had the motivation, and sometimes wanting something is a lot more important than having the real skill."
