How do I enable logging for ssh log in attempts? I have enabled remote logins via SSH on my Mac. But how do I enable logging of all log in attempts? And where is the log?

My /etc/sshd_config has this content:

# Logging
SyslogFacility AUTHPRIV
Login attempts are logged in /var/log/system.log

You'll be able to browse and filter for them through the Console.
