Tools: Setting Up A Professional Macos Dev Environment In 2026

You want a clean, repeatable dev setup on macOS. You want fast installs, predictable updates, and a workflow for shipping real projects. By the end, you will have a working pipeline from your laptop to a live URL.

Update macOS and restart. Open Terminal once to clear first-run prompts.

iTerm2 replaces the default Terminal with split panes, search, profiles, and deep customisation. You spend hours in a terminal each week. A better terminal pays off fast.

macOS ships with Zsh. Oh My Zsh adds a plugin system and better defaults.

Small efficiencies compound. gst instead of git status saves seconds you reclaim thousands of times.

Homebrew makes your macOS setup repeatable. Install, update, and remove tools with one command. No random .dmg downloads. No version guessing.

From this point, check Homebrew for a package before downloading anything manually.

Every deploy starts with a commit. Install Git via Homebrew. The macOS default ships an older release through Xcode Command Line Tools.

SSH gives you secure, token-free Git operations. One setup, zero password prompts.

Different projects need different Node versions. nvm lets you install and switch between them instantly.
