Another of Jobs's maxims at the retreat was "It's better to be a pirate than to join the navy."
He wanted to instill a rebel spirit in his team,
to have them behave like swashbucklers who were proud of their work but willing to commandeer from others.
As Susan Kare put it, "He meant, 'Let's have a renegade feeling to our group. We can move fast. We can get things done.'"
To celebrate Jobs's birthday a few weeks later, the team paid for a billboard on the road to Apple headquarters.
It read: "Happy 28th Steve. The Journey is the Reward.--The Pirates."
One of the Mac team's programmers, Steve Capps, decided this new spirit warranted hoisting a Jolly Roger.
He cut a patch of black cloth and had Kare paint a skull and crossbones on it.
The eye patch she put on the skull was an Apple logo.
Late one Sunday night Capps climbed to the roof of their newly built Bandley 3 building
and hoisted the flag on a scaffolding pole that the construction workers had left behind.
It waved proudly for a few weeks,
until members of the Lisa team, in a late-night foray, stole the flag and sent their Mac rivals a ransom note.
Capps led a raid to recover it and was able to wrestle it from a secretary who was guarding it for the Lisa team.
Some of the grown-ups overseeing Apple worried that Jobs's buccaneer spirit was getting out of hand.
"Flying that flag was really stupid," said Arthur Rock.
"It was telling the rest of the company they were no good."
But Jobs loved it, and he made sure it waved proudly all the way through to the completion of the Mac project.
"We were the renegades, and we wanted people to know it," he recalled.
