.ssh / config: "Bad setup: UseKeychain" on Mac OS Sierra 10.12.6

Question

I am trying to configure my ssh configuration on Mac (Mac OS Sierra 10.12.6) so that it saves the passphrase for my ssh key in the keychain. I could have done this with

ssh-add -K ~/.ssh/id_rsa

But lately, it no longer works. Following this article, the behavior of the ssh configuration on Mac OS> 10.12.2 seems to have changed, and the recommended way to fix this problem is to add UseKeychain yesssh to your configuration. So here is my section .ssh/config Host *:

Host *
  Port 22
  ServerAliveInterval 60
  ForwardAgent yes
  IdentityFile ~/.ssh/id_rsa
  AddKeysToAgent yes
  UseKeychain yes

When I try to ssh to a third-party host, I get the following error message:

$ ssh my-host
/Users/USER/.ssh/config: line 16: Bad configuration option: usekeychain

Any idea why this is happening and how I can fix it? Thank!
