If you’ve ever used a Mac, you probably haven’t noticed the row of app icons at the bottom of the screen.
As every regular macOS user knows, this is the Dock, a now iconic (if rather subtle) feature that keeps essential apps ready, just a click away, as well as any others you want to add, and it’s now officially 25 years old. . . It has become a core element that macOS users have come to expect in each new edition of the operating system, and it has an interesting backstory.
The Dock’s origin story goes something like this: In the late 1990s, Apple was building a new operating system, Mac OS , which was introduced in Mac OS X 10.0 Cheetah. The Dock didn’t always look the way it does now; At first, it was just a row of simple square icons. The polished, shiny design we recognize today came later, thanks to a designer’s prototype, and it was Apple developer James Thomson’s job to turn those ideas into real, working code.
James Thomson is known for creating a popular calculator app called PCalc and had also previously designed a Mac app called DragThing. This app worked like an older version of the Dock, allowing users to keep shortcuts to apps and files visible and more easily accessible on their desktops. It was actually his work at DragThing that got him a job at Apple, where they asked him to help build the Dock.
From Ireland to the iconic
The project, codenamed “Überbar,” was top secret. Thomson recalls in his blog musings about strict measures to keep things secret, including rumors that leaked screenshots could be traced back to specific computers.
Thomson lived in Ireland while working for Apple, but Steve Jobs apparently wasn’t thrilled with a key developer being so far from the company’s headquarters in Cupertino, California (where Apple still resides today). Jobs insisted that Thomson move permanently to the United States, or else. Thomson refused and eventually quit his job before the Mac OS X Dock was completed. Another engineer rewrote it for the final version of Mac OS
Although Thomson did not remain at Apple, the experience helped him revive DragThing for Mac OS X, and PCalc continues to thrive today. The Dock, of course, has become a signature feature of macOS and is a testament to how a simple, easy-to-use design can stand the test of time.
How macOS set the stage for modern interface design
The macOS Dock significantly influenced the evolution of Microsoft’s taskbar design, particularly with the introduction of Windows 7 in 2009. Before this, the Windows taskbar was primarily a space for opening program windows and the Home button (which turns 31 this year!). but Apple’s Dock demonstrated how combining app shortcuts with live interactive icons could make using an operating system easier and more intuitive.
Inspired by the Dock’s ability to merge app launching and multitasking, Microsoft revamped the Windows 7 taskbar to include pinned apps, allowing users to keep frequently used programs accessible at all times, a feature that It still exists in Windows 11 today and is unlikely to go anywhere anytime soon.
For all of Windows 7’s (well-documented) flaws, this change not only modernized the Windows interface but also showed how a company’s innovation can drive user-centered design improvements that everyone in the industry embraces. After all, the interface of virtually every Android phone on the market today is clearly “inspired” by the tile-based UI of the original iPhone, because it just works.
The 25-year journey of the macOS Dock is a testament to how well-thought-out design can leave a lasting mark, not just on its own platform but across the entire technology landscape. From influencing the Microsoft taskbar to shaping the way we interact with our devices every day, the Dock remains an iconic piece of digital history. As technology continues to evolve, I’m excited to see how companies, including Apple, build on these foundations and create new features that redefine the way we interact with our devices and the software they contain for years to come.
If you are interested in learning more about how the Dock was developed, I would really recommend reading James Thomson’s accounts on his blog.
