Every macOS install comes with its own implementation of OpenSSH, so you don't need to install any third-party software to use it. Just open a Terminal window and jump in! Because of this, you can use the same commands as specified in the Linux client section to access the cluster and transfer files.
Generating a public/private key pair
Generating a public/private key pair is identical to what is described in the Linux client section, that is, by using the ssh-keygen command in a Terminal window.
