I want to password protect my mac, but I don't want to use the Multiuser feature as I'm the only that use this machine.
However, sometimes I go out for lunch and leave my mac with my work just there.
Is there a way to proctect the mac? so that noone can enter?
I saw an extension called Password Security (or something like that) I tried to install it but an error message appears saying that my diskk do not support this feature.
