The weird thing is that the UNIX core of MacOS would lend itself really well to tinkering. It's a shame that Apple lobotomizes all the hardware they sell with locked down firmware...
It's why I much prefer MacOS over Windows. The command line makes sense. The file and folder structure makes sense. The defaults can be a little bit weird but a little configuration can help me feel right at home.
Ironically, I found macOS to be a lot more technical than Windows. It's how I got my start with Linux. At least changing the default browser changes the default browser. I'll be using macOS and Linux side by side.
