Locking your Unattended Mac

For those who are used to the Windows machine, there are some short cuts that would lock your PC when you leave it un-attended. For the Mac however, it's hard to find such shortcuts. I have researched and found a few ways of locking your mac.

1. Sleep your computer. You can refer to the keyboard shortcut post here. Do note that once your computer goes to sleep, so does your upload/download. The equivalent is also to close the lid of the Mac
   
2. Click on your account name on the top right hand corner of the Mac, and click on Login Window.
3. Please refer to the securing your mac post here to enable password prompt for the screensaver. After which, use your Finder, click on the Macintosh HD, and goto /System/Library/Frameworks/ScreenSaver.framework/Resources/, and drag the ScreenSaverEngine application to your toolbar. If you need to lock your computer, just click on this icon to activate the screensaver. Since you have enabled the password prompt, it will prompt you for the password if you touch the Mac.

Hope this helps...
