Shit, I am feeling really old today. macOS was released 20 years ago. Of course, it was called “Mac OS X” back then 😄.
I never worked with MacOS 9 myself, but I rembember driving to Düsseldorf to get one of the first copies of MacOS X Tiger in 2005. Back then I had a PowerPC Mac Mini. I remember feeling excited. After years of using a Linux desktop system, it was great to finally have a well-designed graphical user interface, but at the same, don't miss out on the powerful UNIX tools.
Nowadays Windows has caught up a lot with “Windows Subsystem for Linux(WSL)” and their increased support for Open Source software and services. But Apple has a revival of their with their new ARM hardware — even though macOS Big Sur is not so great 😞.
