While working in a computer lab, I have had the occasions where I had to leave the desk. I wanted a quick way to lock my computer’s screen but didn’t know how. Fortunately, I found directions to do it at OSXDaily.
The directions are pretty easy. Go to System Preferences -> Security & Privacy -> check “Require password after sleep or screen saver begins” and choose a short interval. Close System Preferences.
The article mentions using the keyboard shortcuts depending on the type of Mac you have:
- Control + Shift + Eject
- Control + Shift + Power
I prefer the Hot Corner method. You can just drag the mouse cursor to a corner of the screen, such as the lower left corner. To activate it, go to System Preferences -> Mission Control -> Hot Corners… Then select a corner and choose “Put Display to Sleep” (or “Start Screen Saver”).
In a separate article, they showed how to add a personal message to the lock screen in case you lose the computer. That way people would know who the computer belongs to and how to contact you. Simply go to System Preferences -> Security & Privacy -> make sure the General tab is displayed -> click on the lock at the bottom and enter your password -> check “Show a message when the screen is locked” -> Set Lock Message…
