Configure SSH to use SSH key to access Git on MacOS

Working with Git will make it more efficient using SSH keys, since you do not have to constantly enter in your username and password or personal access token. Make sure your Git site URL is set to use the SSH URL for your repo.

1. Open Terminal
2. Create the .ssh directory, if you don't already have

   mkdir ~/.ssh

3. Create and/or edit the ssh config file (use your favourite editor)

   vi ~/.ssh/config

4. Copy the config info below and paste it into the ssh config file

   Host github.com
   Hostname github.com
   User git
   IdentityFile /opt/ssh/[id_rsa]

5. Save and exit the config file

   :x!
