Fira VS inter

I've been using Fira Sans.

Fira Sans Medium: https://github.com/mozilla/fira

Fira Sans/Code/Mono (F) [OFL]

if you still want to use a font that looks like Fira Code, you can try Fira Mono instead of Fira Code. I think Fira Code is based off of Fira Mono to begin with

An example is Fira Mono.

Have a look at Fira. It has a hairline weight that is really thin.

Fira Sans. I set my entire system font to Fira Sans because I like this font.

I couldn't agree more. I've been using it as my go-to font for web development (which is its exact design purpose) for years. Nothing looks bad in Inter[0]. It's an easy win.

The best features for web dev are great readability across its variety of weights (0-900 in CSS) from a single font file, along with a huge set of glyphs, ligatures, special numbers, etc. if you want them.

Yeah no... macOS doesn't have a font that looks uncomfortably tall like that. Use Inter at 9pt font size if you really want the macOS look.

Now you also need to download and install 'Inter' font. Go here: https://rsms.me/inter/ And download it, install it. We will use it later.

It’d be nice if something like Inter[0], which is specifically designed for onscreen/UI usage, were bundled with each OS and could be assumed to be present, making it unnecessary to include Arial or Helvetica in one’s stack.

If you are really trying to mimic macOS then you should try Inter. Current version is 3.19 but the much improved version 4.0 is coming out very soon (you can download the latest beta here). This font is pretty much an open-source alternative to Apple's SF fonts and they render at the correct size on all platforms. With a little tweaking of the font rendering, you can make it look almost identical to macOS.
