There are two ways of installing meld on osx (May 2023), using brew and .dmg package (from @yousseb). Since I found https://yousseb.github.io/meld/, I've installed it with .dmg package, but having macOS Ventura Version 13.4 (22F66) in place, it's not even starting for me. So I tried brew installation, and the application is working as expected, including symlink to start it from the terminal.
Using brew formulae: https://formulae.brew.sh/cask/meld
brew install --cask meld
# set meld as your default git mergetool
git config --global merge.tool meld
Requires: macOS >= 10.13 meld has been officially discontinued upstream. It may stop working correctly (or at all) in recent versions of macOS.

Alternative method (by @yousseb), try
.dmgpackage yourself: https://yousseb.github.io/meld (caveat: project haven't been updated since Jul 2022). -
Legacy methods (including old osx versions): https://gist.github.com/p1nox/6102015/4fa2a9ba9379879a35e113921770c85e09861e8a
- If meld doesn't start from terminal, try this, modify the
/usr/local/Caskroom/meld/3.19.2-r6,osx-15/meld.wrapper.shscript installed by brew to the following:
#!/bin/sh
rm -rf ~/Library/Saved\ Application\ State/org.gnome.meld.savedState
exec '/Applications/Meld.app/Contents/MacOS/Meld' "$@"
