In Mac OS X, if I don’t touch it for a while, it will lock the screen and one must use password to unlock it, but this kind of log in is not recorded by last command. I want to know if anybody tried to break into my MacBook when I am not in front of it. Is there any way I can log such attempts?
As I was investigating a server that is rebooting in a regular fashion, I started looking through the “last” utility but the problem is that I am unable to find what the columns mean exactly. I have, of course, looked through the man but it does not contain this information.
