3. Oh My Zsh

Supercharge your terminal with styles, plugins and features! Since Apple replaced Bash with Zsh in 2019 and it installs with a single shell command, this is a no-brainer. You can pick from a boatload of themes — or just use the default one like me, it’s plenty good!

Basically if you ever saw someone using a fancy terminal, chances are that he was using Oh My Zsh.

Plugins are also a huge part of the Oh My Zsh ecosystem. My must haves are:

git for displaying what branch I'm on + if there are any changes wd - shorthand for warp directory allows you to set up warp points in your file system and then jump to them from anywhere! If nothing else, this will prettify your Terminal — and who doesn’t want that?! Get Oh My Zsh now!
