You can simulate this by adding the `-webkit-font-smoothing: antialiased` CSS rule to any website when using Safari or Chrome. Lots of websites already do this though, so you can use the value `subpixel-antialiased` to revert the text to that mode instead. https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth To really appreciate the difference, I recommend turning on screen zoom with ctrl-scroll in the accessibility system prefs. You’ll see the effect of SPAA as colouring on the left and right edges of text.
