Apple stole everything from Xerox.
No, they did not. Apple had been working on a GUI for two years before the visit to Xerox's PARC for which they paid about $7 million in common stock for the rights to use what they learned. No theft occurred. The Apple interface was significantly different from the Star interface and included the top menu bar, submenus to menus, drag and drop, the trashcan metaphor for deleting files, and draggable windows which did not exist in the Star interface.
