This recipe allows you to use the ssh-agent from homebrew with the auto generated SSH_AUTH_SOCK in /private/tmp. It works because disabling com.openssh.ssh-agent doesn't stop launchd from allocating SSH_AUTH_SOCK. com.homebrew.ssh-agent spawns a shell to remove the socket and then execute the homebrew ssh-agent.

1. Install openssh from homebrew
2. Disable the built in macOS agent: launchctl disable gui/$UID/com.openssh.ssh-agent
3. Copy com.homebrew.ssh-agent.plist into ~/Library/LaunchAgents
4. Enable the new agent: launchctl bootstrap gui/$UID com.homebrew.ssh-agent.plist
5. Ensure that the correct agent is running:
