How to Setup Git and GitHub on macOS in 5 Minutes

Install Git

$ brew install git

Set up global configs

You have to do this only once.

$ git config --global "Steve Smith" # Name
$ git config --global # Email
$ git config --global core.editor nvim # Default editor (Neovim here)
$ git config --global core.autocrlf input # Line ending

Create SSH keys on your machine

Open the terminal and paste the following text

$ ssh-keygen -t ed25519 -C ""

Accept the defaults. Ignore the passphrase.

Start the ssh-agent

$ eval "$(ssh-agent -s)"

Open SSH config file

$ nvim ~/.ssh/config

Past the text below in your config file

Host *
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_ed25519

Save and exit.

Add your SSH private key to the ssh-agent.

$ ssh-add ~/.ssh/id_ed25519

Copy the SSH public key to your clipboard.

$ pbcopy < ~/.ssh/

Add SSH keys to GitHub

Visit GitHub keys and click on New SSH key button.

  • Enter a meaningful title

  • Select Authentication key as 'Key type'

  • Under the Key segment, paste from your clipboard.

  • Click on Add SSH key button.

Check your SSH connection to GitHub

$ ssh -T

On a successful connection, you will get a message like this.

$ Hi Steve Smith! You've successfully authenticated, but GitHub does not provide shell access.
