Setup

0. Allow your terminal full disk access.

Example if using iTerm:

System Settings > Privacy & Security > full disk access > switch on for iTerm

1. Enable SSH Server on macOS

   Ensure the SSH server is enabled on your macOS system:

   sudo systemsetup -setremotelogin on
   

   Verify SSH is enabled:

   sudo systemsetup -getremotelogin
   

   The output should indicate that remote login is enabled:

   Remote Login: On
   

2. Set Up SSH Access

   Ensure your SSH keys are set up properly:

   • Generate an SSH key pair (if you don't have one, typically you already should have a key):

     ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
     

   • Copy the public key to the authorized_keys file:

     cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
     

     Note: the pre existing public key could have a different name. Such as

     cat ~/.ssh/id_ed25519.pub >> ~/.ssh/authorized_keys
     

3. Verify SSH Configuration for Git Access

   Ensure the following configurations are set in your SSH configuration file (/etc/ssh/sshd_config):

   PasswordAuthentication no
   PubkeyAuthentication yes
   ChallengeResponseAuthentication no
   

   Restart the SSH service to apply the changes:

   sudo launchctl stop com.openssh.sshd
   sudo launchctl start com.openssh.sshd
