There is only so much rounding of borders you can do in the terminal! On a 16” MacBook, you can’t have Activity Monitor take up less than about 2/5 of the width of the screen! There is so much padding around every single element.
I don’t need pretty buttons, I need usability and readability. Without having a 50” display!
Somewhere along the way everything got dumbed down and all the info removed. It’s some condescending ‘so dumb ppl can take it in’ marketing bs I hear from time to time. And it sucks! I also doubt it’s true. Fashion be fashion.
