I'm trying to find out if someone has hacked my computer. In case I get the following message in my Terminal window: "Last login: Tue Sep 30 02:02:18 on console" does that mean a person has logged in, or could it be an automatic programme running?
Popmoi, the last login on console is exactly that: Somebody (likely you) logged into a bash session on your computer at 2:02:18 on Sep 30. Generally, 'console' is shown for the first shell login and then ttys000 would be the next. I see this every login/reboot for my Terminal group, which opens two bash sessions in different tabs.
