I'm using macOS Sierra and when I try to view failed login attempts, grep doesn't return any results because the keyword has probably changed or I'm looking in the wrong place. Does anyone know where/how to find these?
I've looked at similar questions but they are all out of date. The most recent post I found suggested trying these but neither produced any results.
grep "Failed to authenticate user" /var/log/system.log grep "authentication error for" /var/log/system.log
