Mac OS X arrived 20 years ago today – here's how it's changed since then
What you need to know
- Apple released Mac OS X way back on March 24, 2001.
- 20 years later this video shows just how macOS has changed over the years.
March 24, 2001 saw Apple drop what would become the foundation that Macs would use for the next 20 years and, likely, much longer. Mac OS X Cheetah arrived alongside a new interface, dubbed Aqua. Love it or loathe, it, Aqua started Apple off on a run of design choices that ultimately led to what we saw on iPhone in 2007. iOS 14 has changed a lot since then, but wait until you see how macOS has changed since 2001.
That's something Martin Nobel set about showing us in a new YouTube video.
Introducing the Evolution of macOS.
Apple has only recently started to change the underpinnings of macOS thanks to a filesystem switch to APFS and app signing features like Gatekeeper. But you'll see some big changes across the interface as well. Especially if you weren't a fan of Aqua way back when!
Anyone buying one of Apple's best Macs today will receive macOS Big Sur as well as future updates to come. Who knows what we'll all be using 20 years from now – it'll probably look more like iPadOS than Mac OS X, that's for sure.
Were you around back in 2001? I want to hear your thoughts on Mac OS X and Aqua. I wasn't in the Apple world back then, but I do remember controversy. It wouldn't be a Mac software update without controversy, would it?
