Re: 'and even then every design professional would laugh'
The colour management and fonts were a very big deal in that space. Windows really couldn't do that until about 10-15 years ago.
But now, macOS Mojave can't even render fonts properly, as they removed subpixel rendering. Perhaps that's not completely necessary on a Hi-DPI screen, but most Macs don't have "Retina" displays.
It's time Apple just admitted that they don't want to make laptops and desktops anymore, and concentrate on the phones and tablets that are their core business.
