Steve Wozniak talked about returning to Apple Lossless Audio CODEC (ALAC), in a recent interview given to an American publication, he being one of the well-known co-founders of the company from Cupertino, the disputes with Steve Jobs motivating him to leave Apple many decades ago.
Although the misunderstandings regarding the direction in which Apple is heading motivated him to appear at the time as the American company, it seems that in 2011 Steve Jobs asked him Steve Wozniak to return to Apple to contribute to the creation of revolutionary products for millions of customers.
Steve Wozniak says that Steve Jobs asked him if he wants to return to Apple, but the call is presented more as an "opportunity" offered to Wozniak than as a call based on a need that the Apple co-founder could cover with his experience.
Steve Jobs has asked me questions along the lines [of coming back to Apple] close to his death, and I told him no, I love the life I have.
Steve Wozniak declared that he refused Steve Jobs' offer, as you already know very well, stating that he was never tempted to return to Apple to participate in the projects that made the company so famous in recent years all over the world.
Speaking also about the movie Steve Jobs, for which Steve Wozniak was a paid consultant, he claims that in many scenes he saw his "real" friend, even though most of the movie contains inventions of the screenwriter and not real events from the life of the legendary Apple CEO.
