Oh My Zsh

Sticking with terminal tools, this one is a must-have. Starting with macOS Catalina, Macs now use zsh as the default login shell instead of bash. So it's worth checking out Oh My Zsh which supercharges your zsh config with helpers, plugins, and themes.

I'm currently using the powerlevel10k theme, which not only makes your terminal look slick but it adds all sorts of configurable segments to your prompt (e.g. git branch, git status, env info, IP address, current time, disk usage, etc).

Two plugins I'd recommend include zsh-syntax-highlighting, which adds syntax highlighting to your commands, and zsh-autosuggestions, which suggests commands as you type based on history and completions.
