When you open up your MacBook, MacBook Air, or MacBook Pro, the glowing Apple logo on its hood sits upright so that everyone in Starbucks knows that you’re using a Mac. However, it hasn’t always been that way. There was a time when Apple logos were upside down on the lid of Apple notebooks, until Steve Jobs realized his mistake.

Joe Moreno, a former Apple employee, has taken to his blog to explain the story behind that upside down Apple logo on late Apple notebooks.

About a dozen years ago we had some discussions at Apple about the placement of the logo on the back of Apple’s laptops. […] Apple has an internal system called Can We Talk? where any employee can raise questions on most any subject. So we asked, “Why is the Apple logo upside down on laptops when the lid is open?”

The answer, of course, is because Steve Jobs wanted it that way. We’re well aware of Steve’s attention to detail and how much he obsessed over the littlest things, and this was one of them. Steve wanted to make sure that when a user sat down in front of their Mac, the Apple logo was facing towards them; he didn’t care how an onlooker saw it.

Why was upside down from the user’s perspective an issue? Because the design group noticed that users constantly tried to open the laptop from the wrong end. Steve Jobs always focuses on providing the best possible user experience and believed that it was more important to satisfy the user than the onlooker.

But years later, Steve reversed his decision and turned the Apple logo around. Moreno concludes that “opening a laptop from the wrong end is a self-correcting problem that only lasts for a few seconds. However, viewing the upside logo is a problem that lasts indefinitely.”

According to author Ken Segall, who worked closely with Jobs while with an advertising agency used by Apple, this was one of Steve’s early mistakes. In his new book, Insanely Simple: The Obsession That Drives Apple’s Success, Segall recalls a meeting with Steve over the logo’s positioning on a PowerBook:

Which was more important — to make the logo look right to the owner before the PowerBook was opened, or to have it look right to the rest of the world when the machine was in use? Look around today and the answer is pretty obvious. Every laptop on earth has a logo that’s right-side up when the machine is opened. Back then, it wasn’t so obvious, probably because laptops were not yet ubiquitous.
