List failed login attempts on Mavericks I want to see if somebody has tried to log in on my computer, which is running Mavericks. I am primarily interested in tracking ssh log in attempts, as well as tracking people physically typing passwords on my keyboard to try to log in.

I have seen How to log login and logout on Mavericks?, but last seems to list only successful logins, or at least it mostly shows successful logins.

I have also seen an answer about looking in system.log or "all messages", using the console utility, but those files/messages seem very cluttered.

You can use this Terminal command:
