Yes it does! Although I recommend not installing asdf via homebrew and installing it via git instead. It makes updating more seamless.

I just joined a company in the past few months that uses Macs and pretty much all dev environment documentation insists on using ASDF. I had a lot of problems, and am still having one or two, in a few of the codebases I need to work in.

I think the main thing is just having consistent documentation, especially for global settings.

But other than that it definitely "works" on MacOS; can't comment on fish, I use zsh.

This is my setup, and it works great! Install was flawless aswell, no trickery needed on my behalf. What problem did you run into?

Yep, I use adsf and fish on MacOS installed via Homebrew. Works great.
