Xerox PARC Visit

Steve Jobs and several Apple engineers, in exchange for Apple stock options, visited Xerox PARC and were shown groundbreaking technologies including the graphical user interface (GUI), object-oriented programming, and networked computers.

Significance

This visit was a pivotal turning point, deeply inspiring Jobs and the Macintosh team to abandon their text-based interface and pursue a mouse-driven GUI, directly influencing the Mac OS's core design.
