Jobs' unconventional work style and ability to forecast a market made him a renowned business leader. His visit to Xerox Corporation's Palo Alto Research Center (PARC) with a group of Apple engineers in 1979 may be the most noteworthy example. According to some reports, this visit was in exchange for allowing Xerox to acquire 5% of the firm for $1 million. Inspired by his visit to Xerox, Jobs would incorporate the characteristics into his company's new line of computers. Jeff Raskin began the Macintosh project in 1979 with the goal of creating an easy-to-use, low-cost system for the typical customer, and Jobs quickly saw it as the right product for his ideals.

Jobs personally unveiled the first Macintosh in January 1984, during a large media campaign anchored by the now-famous TV advertisement based on George Orwell's 1984. The Macintosh, subsequently abbreviated as Mac, was the first commercially successful personal computer with a graphical user interface (GUI) and a mouse, as opposed to its predecessors' command line. This was a critical stage in the evolution of the personal computer industry. He introduced GUI, built-in screen and mouse into a personal computer.
