Wednesday is the twentieth anniversary of Mac OS X. And those who went though the many versions over the decades can download some reminders. Every major new version came with a fresh wallpaper, and they’re all available for free.

OS X, the most important piece of software in Apple history, turns 20 today.

Going on sale in its full, public version on March 24, 2001, Mac OS X 10.0 — code-named Cheetah, the first of many cat-themed names — transformed Apple’s operating system forever. It brought user interface enhancements that persist to this day, as well as technological advances that form the backbone of Apple’s current operating systems. In fact, OS X paved the way for today’s post-PC devices, from the iPhone and Apple Watch to HomePod and Apple TV.

While Apple eventually ditched the “OS X” branding for “macOS,” and switched from naming Mac software after big cats to California locations in 2013, Cheetah’s impact continues to be felt two decades after its introduction.

While the latest version of Apple’s fantastic (and free!) music production suite, GarageBand, has lost some functionality like podcasting and Magic GarageBand, it still has plenty to recommend it for those new to music or old vets alike.

It’s a pretty heady set of music learning; here’s how to access it. Getting really good at your instrument will take more than watching a video or three, but this is a great start if you want to try your hand at the guitar or piano.
