Steve Wozniak played a vital role in Apple's success up until 1985 when he left the highly successful personal computer manufacturer. Wozniak was a home computer enthusiast and engineer who inspired Steve Jobs to see a vision of how these computers could benefit people's lives.
However, after a short few years, Apple was at the forefront of computer technology globally, alongside their biggest rival IBM. But as successful as Apple seemed to be, Steve Jobs and Steve Wozniak didn't see eye to eye on what the Apple computers needed to be. Jobs wanted each computer to be as minimalistic as possible with no cooling fans, and only 2 ports to connect a printer and a modem, whereby Wozniak favoured many ports to allow the user to decide what they would like to connect.
In 1981, Steve Jobs was involved in a severe plane crash which rendered him out of Apple for 2 years due to his injuries. During this time, Wozniak explained that Jobs was far too far ahead in the ways that made him feel that he was far too far behind to continue at Apple, hence his resignation.
