I use Windows and macOS both daily and it's truly baffling to me that anyway could consider Windows software quality to crush the Mac -- either first party or third party. macOS has no shortage of bugs but compared to Windows it works like a dream.
As one example of many, Night Light (Windows' version of adjusting your screen to be warmer at night) has been broken for me, for 5+ years. I mean literally it just never works on its own. The only way to kick it into working is toggling HDR on and then off, every single time I wake it up.
I would guess it's just my configuration but I built a second PC from totally new parts, and got a different monitor, and installed Windows 11 instead of 10, and it's still broken.
I switched from a Windows laptop to a Macbook. When you closed the lid on the Windows one if whirred for about 30 seconds trying to sleep and if you opened and closed too quickly the os crashed and needed restarting. Mac you just open and close as you like and there's your stuff straight away.
Nothing's perfect but Mac seems good at the basics of running quickly without crashes.
That is how I had interpreted "And certainly not software quality" - that the PC not only competes but crushes the Mac.
