How to migrate from Homebrew to Nix

#homebrew #brew #nix #nixos

I'll be honest with ya'll, you don't wanna get away from Homebrew completely, yes, I'll explain!

I've been using Nix package manager in all my MacOS machines about 3-4 months and I always kept Homebrew installed. You see, Nix is a very good package manager and with its home-manager, it becomes a good config farm as well. However, installing & managing GUI & unfree apps via Nix has been a quite painful experience for me. Sometimes, it wouldn't run properly, crash or wouldn't even start. Also, Nix doesn't have most of GUI packages that Homebrew has. Therefore, I keep homebrew and use it only for its "casks" registry to install GUI & unfree apps whereas having nix to manage dot file configurations and cli apps.
