.ssh/config: “Bad configuration option: UseKeychain” on Mac OS Sierra 10.12.6

The accepted answer helped me but did not completely solve my problem because I had multiple options that were bad. Here is an example of what it might look like if you have this issue:

  IgnoreUnknown AddKeysToAgent,UseKeychain
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_rsa
