Intic Lock can lock your Mac from the Dashboard. After double-clicking it shows the login screen. Your Computer will only resume the session after you entered the correct password.You can also put your computer into sleep mode at the same time to save battery power.
Intic Lock features a neat-looking user interface and comes in six different colors.
ANDREW SCOTT Very useful: just was I was looking for.
I don't like to leave the lock-on-sleep setting switched on on my Macs because I find it inconvenient but sometimes I do need to lock it when I know I'll be away from my screen for a while. This widget lets me do so quickly without needing to have fast user switching activated. This is an advantage on my MacBook Air's smaller screen. (Version 1.3)
