Set up this Mac

DeepBlueish runs on your own computer, not in the cloud. On a Mac that doesn't have it yet:

Easy way: ⬇︎ Download the setup script, then in your Downloads folder right-click it → Open (first time only — it's unsigned, so macOS asks). Terminal opens and does everything: installs Homebrew, Node, Stockfish, signs you into GitHub, fetches the app, and opens the dashboard.

Or by hand — open Terminal (⌘-space, type "Terminal") and paste these five lines one at a time:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install node gh stockfish
gh auth login
gh repo clone jeffreyashton/DeepBlueish ~/DeepBlueish
cd ~/DeepBlueish && node bridge/server.js

Then visit http://localhost:4002. Already installed? Just run the last line.
