I actually disagree with the assessment that fonts 'look better' on macos. They are blurrier and inconsistent. The linked tweet explains all this. I don't know how the conclusion can be 'it looks better' when it's harder to read.
I use the same font on macOs and Windows in Obsidian and for coding in PyCharm / Rider / CLion, i.e., PragmataPro Liga and it looks significantly better on macOs. JetBrains Mono does look much better too.
I use a bitmap font without antialiasing on macos and it's crystal clear. Selecting something more 'normal' or 'modern' then turning on antialiasing turns it into a blurry mess.
Agreed so much. The total neglect for people still using lo-DPI (a macos term) screens is just plan insult. I see a lot of excuses for axing subpixel hinting with the solution being, "buy a hi-DPI screen."
Even high dpi monitors are rough. Using a non-integer scaling, you run into weird flickering and inconsistent widths as things land on even (single) or odd (two) pixels. Using a 2x scaling, it's still blurry, just the fuzzy edges are half as wide. You can see this most strikingly when hairline black glyph stems turn into two pixel wide gray stems... and the adjacent stem lands on an even pixel so it's perfect. When this happens to double letters in words, it makes my brain think "This kinda looks like the word 'moon' but it can't be since the two o's aren't the same so it must be misspelled"
