This will take you 30 seconds.
Picture the scene, you’re working away in a public place, office space or a coffee shop, somewhere like that, and you have to get up to carry out some demeaning task (getting yourself a fresh brew etc).
What do you do with your Mac?
Shut the lid? That’ll stop any processes and put it to sleep.
Log out? The same thing.
Start your screensaver? Could do, but that involves going to System Prefs > Desktop & Screensaver and clicking ‘Preview’, unless you have a keyboard shortcut or hot corner setup, and even then you need to make sure you have ‘Require password X MINS after sleep or screensaver begins’.
Why not have a little handy lock icon in your menubar that you can lock your screen with? This puts the screen to sleep, requires a password when it wakes, but keeps the computer, and your processes running – perfect for a few mins away (but keep an eye on your Mac, beware thieves!).
1 Click ⌘Space to open spotlight, type ‘Keychain’. This will open the Keychain app.
2 Hit ⌘, – that’s command + comma, or go Keychain Access > Prefs and check ‘Show keychain access in menubar’. This puts the lock icon in your bar.
Click that and you can now ‘Lock Screen’.
Whilst your screen is locked and you need your password to unlock it, your downloads keep downloading, iTunes keeps playing and anything else you were doing carries on behind your locked screen!
So simple but many Mac users don’t know about it, add this today, guarantee you’ll use it.
