macOS doesn't even support subpixel rendering since Mojave from what I understand. And even prior to that change, simple XP ClearType and beyond has always looked far superior to macOS/freetype rendering in my opinion.
And it introduces tons of complexities and tradeoffs, namely that it breaks all scaling, adding ugly color fringes. I remember it was such a pain on Windows to remember to disable subpixel rendering every time I needed to take a screenshot to paste into documentation.
And say what you will about ClearType: at least you can turn it off. I recall trying so hard to do the same for my Mac only to find out my instructions, including massive config changes, sadly no longer worked due to a version bump of the OS.
