> Well, Mac OS users lived with this serious rendering bug for more than a decade Er, kinda kinda-not. A lot of this article discusses subpixel AA which has been disabled by default on high DPI displays since they were introduced, for all Macs for several years, and the setting hidden in UI and eventually fully removed. Light on dark text still renders perceptually bolder regardless of measurement, and many dark mode guidelines rightly recommend using slightly lighter font variants in dark mode where that perception feels off. I made this choice with my site even where the system font is used for prose text, specifically because text in dark mode looked heavier for me. But there wasn’t a bug… this was consistent in Safari and rendering contexts that bypass macOS text rendering.
