Looks like the issue appeared after updating git from brew. I tried it on a different mac laptop, git 2.18 still used English, but after updating to 2.19 it started using secondary language. A quick search revealed that brew changed how it builds git recently. I think, it just didn't include i18n by default before, so I never noticed this. Here's the history of formula changes: https://github.com/Homebrew/homebrew-core/commits/master/Formula/git.rb Also, I found this thread https://github.com/Homebrew/homebrew-core/issues/31980 Anybody here familiar enough with the build process and dependencies of git to pinpoint what exactly is causing this and how to fix it?...
