Working long hours being single helps because your time is yours. Once you have a family your time isn't all yours anymore. Most of the Mac team, we were in our mid-20's, most of us were single, and we were able to essentially devote our lives to it.Andy Hertzfeld
But I think Steve's main contribution besides just the pure leadership is his passion for excellence. He's a perfectionist. Good enough isn't good enough. And also his creative spirit. You know he really, really wants to do something great.Andy Hertzfeld
But typically for a project like the Mac, the size we had was pretty good. And it has different stages. The team grows as you have to write manuals and do testing... though the Mac had no formal testing.Andy Hertzfeld
Apple was our benefactor at starting General Magic, but about a year later decided they would rather BE General Magic and tried to make us blink out of existence... which we eventually did, but it took a few years.Andy Hertzfeld
The Macintosh having shipped, his next agenda was to turn the rest of Apple into the Mac group. He had perceived the rest of Apple wasn't as creative or motivated as the Mac team, and what you need to take over the company are managers, not innovator...Andy Hertzfeld
We were developing an innovative Personal Information Manager called Chandler but a couple years ago I took off from that to do a project writing down my memoirs essentially, reminiscing about the development of the Macintosh.Andy Hertzfeld
